Hello! My name is Domingo. How can I help you today?

User

Hi Domingo. I have a slight problem with my excel file I'm hoping you have an answer to

Excelchat Expert
31/05/2018 - 02:07

let's see what can I do for you :)

User
31/05/2018 - 02:08

I have two columns with Yes or No choices in drop down lists. The third column is where comments need to be added if the answer in column 2 is No. I want it so that they must enter a comment before moving on

Excelchat Expert
31/05/2018 - 02:09

I've just replicated your description. Am I correct?

Excelchat Expert
31/05/2018 - 02:10

or have I missed something?

User
31/05/2018 - 02:10

there is also a column (the very first one) pertaining to the speicfic report I am writing Yes/No for

User
31/05/2018 - 02:10

but i dont know that it matters

User
31/05/2018 - 02:11

mainly just need to figureo ut the formula to make it so comments are required for "No" in column 2 there before moving on

User
31/05/2018 - 02:11

I have tried data validation, but could not get it to work

Excelchat Expert
31/05/2018 - 02:11

Ok

Excelchat Expert
31/05/2018 - 02:12

so you fill this table row by row, correct?

Excelchat Expert
31/05/2018 - 02:12

and Only if Dropdown2 is No, a comment should be added

User
31/05/2018 - 02:13

Yes, that is correct. Dropdown 1 will more than likely always be Yes, but No is an option in the evnet it is not

Excelchat Expert
31/05/2018 - 02:13

Ok

User
31/05/2018 - 02:13

If dropdown 2 is No then a comment is added in the next column over on the same row

Excelchat Expert
31/05/2018 - 02:14

is it a custom or standard comment?

User
31/05/2018 - 02:14

Custom, it's user input based on why they chose No

User
31/05/2018 - 02:17

So for example, in the line you have now, if drop down 2 is No as it is there in row 2 I need a message to pop up requiring a comment as to why before they can move on to row 3

Excelchat Expert
31/05/2018 - 02:17

Understood

Excelchat Expert
31/05/2018 - 02:17

Could you please give me a brief moment to validate my solution?

User
31/05/2018 - 02:18

Yes, by all means

Excelchat Expert
31/05/2018 - 02:22

I'm still with you

Excelchat Expert
31/05/2018 - 02:22

almos done

Excelchat Expert
31/05/2018 - 02:22

almost*

User
31/05/2018 - 02:22

Okay great

Excelchat Expert
31/05/2018 - 02:25

Ok

Excelchat Expert
31/05/2018 - 02:25

just to confirm, are you working with excel or a google sheet?

User
31/05/2018 - 02:26

Excel

Excelchat Expert
31/05/2018 - 02:26

Ok

Excelchat Expert
31/05/2018 - 02:27

I have one alternative as my thought solution is not working right now. But I can keep trying a little more if you want.

User
31/05/2018 - 02:27

Yes please

Excelchat Expert
31/05/2018 - 02:27

Great

Excelchat Expert
31/05/2018 - 02:27

Thanks for the patience

User
31/05/2018 - 02:27

I have been able to get it to show "Please add a comment!" into the comment line and a message popping up, but it only works when Yes is selected

User
31/05/2018 - 02:27

NO problem

User
31/05/2018 - 02:28

If it helps my formula is:

User
31/05/2018 - 02:28

=IF(D4="No","","Please add acomment!")

User
31/05/2018 - 02:28

With an error message as well

User
31/05/2018 - 02:29

but it only works for yes, when I change to no it jsut stays there with no message popping up. it need to pop up when changed form yes to no

Excelchat Expert
31/05/2018 - 02:30

This is very similar to my alternative, you can try flipping the condition=IF(D4="Yes","","Please add acomment!")

User
31/05/2018 - 02:31

That made it so that it shows up when changed to no, but no error message shows up

Excelchat Expert
31/05/2018 - 02:32

that's right.

Excelchat Expert
31/05/2018 - 02:32

at case you can try this:

Excelchat Expert
31/05/2018 - 02:32

=IF(D4<>"No","","Please add acomment!")

Excelchat Expert
31/05/2018 - 02:32

alright

User
31/05/2018 - 02:33

Let me try

Excelchat Expert
31/05/2018 - 02:33

I finally made my solution work

User
31/05/2018 - 02:34

okay, can we start fresh and show me on here? changing the condition again and trying tio duplicate it on a line messed it up

Excelchat Expert
31/05/2018 - 02:34

definitively!

Excelchat Expert
31/05/2018 - 02:35

ok. so what you need to do is the following

Excelchat Expert
31/05/2018 - 02:35

Select the range you want to apply the data validation

Excelchat Expert
31/05/2018 - 02:35

I've set to light blue

Excelchat Expert
31/05/2018 - 02:35

the first row is not necessary

Excelchat Expert
31/05/2018 - 02:36

Now, you have to create a custom formula data validation and insert the following formula:

Excelchat Expert
31/05/2018 - 02:36

"=NOT(AND(C2=2,ISBLANK(D2)))"

Excelchat Expert
31/05/2018 - 02:37

sorry, should be this:

Excelchat Expert
31/05/2018 - 02:37

"=NOT(AND($C2=2,ISBLANK($D2)))"

Excelchat Expert
31/05/2018 - 02:37

the $ symbols

Excelchat Expert
31/05/2018 - 02:37

don't forget :)

Excelchat Expert
31/05/2018 - 02:38

I've just applied the data validation

Excelchat Expert
31/05/2018 - 02:39

I'm sorry, this should be the formula:

Excelchat Expert
31/05/2018 - 02:39

=NOT(AND($C2="No",ISBLANK($D2)))

Excelchat Expert
31/05/2018 - 02:39

was testing with a "2" :)

User
31/05/2018 - 02:40

i applied it to my sheet and nothing happened

User
31/05/2018 - 02:40

There is also a fucntion that highligths the comment line if blank right now, could this be messing it up?

Excelchat Expert
31/05/2018 - 02:41

it shouldn't.

Excelchat Expert
31/05/2018 - 02:41

did you changed the $C2 and $D2 with your respective cells in your sheet?

User
31/05/2018 - 02:41

that formula does nothing to my sheet even if I try with jsuto ne line

User
31/05/2018 - 02:42

my cells are different in this excel

Excelchat Expert
31/05/2018 - 02:42

wHich are your cells?

User
31/05/2018 - 02:43

here hold on

User
31/05/2018 - 02:43

adding file for you

Excelchat Expert
31/05/2018 - 02:43

User
31/05/2018 - 02:44

dont think I can sicne company document

Excelchat Expert
31/05/2018 - 02:44

its ok

Excelchat Expert
31/05/2018 - 02:44

which column letter is your second dropdown?

User
31/05/2018 - 02:45

here we go

User
31/05/2018 - 02:45

this is what mine looks like

Excelchat Expert
31/05/2018 - 02:47

Ok. Here I can see that Column A is working as expected

User
31/05/2018 - 02:49

Column A isnt important, jsut there as reference, I dont need ot change those values

Excelchat Expert
31/05/2018 - 02:50

which cells do you want to block if the previous is not correct

User
31/05/2018 - 02:51

Now it looks identical to mine.

User
31/05/2018 - 02:51

When any values in column D chagne form yes to no, then a commnetm ust be added to column E

User
31/05/2018 - 02:51

sorry, typing too fast, typos

User
31/05/2018 - 02:52

But column E needs to have the message saying "Please add a comment!" and an error message to notify them to

User
31/05/2018 - 02:52

when changed form yes to no in D

Excelchat Expert
31/05/2018 - 02:53

ok.

Excelchat Expert
31/05/2018 - 02:53

do people modify column D to choose "No" or they pick "No" when filling a new row?

User
31/05/2018 - 02:54

By default they all say Yes, but if it needs to be changed in C or D they can

User
31/05/2018 - 02:54

but only D matters for column E, meaning the comment needs to reflect why they changed from yes to no

User
31/05/2018 - 02:55

still a custom somment and the same issue

User
31/05/2018 - 02:55

comment*

Excelchat Expert
31/05/2018 - 02:55

Got it. in that case, we can change the validation to be on Column E specifying that if Colum D = NO then Column E mustn't be empty

Excelchat Expert
31/05/2018 - 02:56

it will not trigger a warning but will add a red corner to the cell in column E.

User
31/05/2018 - 02:56

That would be perfect, as long as they are notified to add a comment to E when D changed to no then its good

User
31/05/2018 - 02:56

is this the same formula as posted by you above?

Excelchat Expert
31/05/2018 - 02:57

similar, I'm adjusting it now

User
31/05/2018 - 02:58

okay

Excelchat Expert
31/05/2018 - 02:58

or

Excelchat Expert
31/05/2018 - 02:58

a better alternative

Excelchat Expert
31/05/2018 - 02:59

dd a conditional formatting con the comment IF Accuracy = No

Excelchat Expert
31/05/2018 - 02:59

what do you think?

User
31/05/2018 - 02:59

Im not sure what you mean

User
31/05/2018 - 02:59

I tohught about condition formatting but ive never used it

Excelchat Expert
31/05/2018 - 03:00

User
31/05/2018 - 03:00

Ok

User
31/05/2018 - 03:04

Need some time?

Excelchat Expert
31/05/2018 - 03:04

Done

Excelchat Expert
31/05/2018 - 03:04

rry for dissapearing

User
31/05/2018 - 03:05

That's okay

Excelchat Expert
31/05/2018 - 03:05

Excelchat Expert
31/05/2018 - 03:05

Excelchat Expert
31/05/2018 - 03:05

=AND($D1="No",ISBLANK($E1))

Excelchat Expert
31/05/2018 - 03:06
