Do you have sample data which we can use to illustrate how to solve this problem?

User
25/09/2018 - 02:20

The sheet I am working in is huge so I can not upload

Excelchat Expert
25/09/2018 - 02:21

Okay.

User
25/09/2018 - 02:21

Example.

Excelchat Expert
25/09/2018 - 02:21

But you can just give an example of how the data is structured.

Excelchat Expert
25/09/2018 - 02:21

Just a few rows are enough, just for illustration purposes.

User

I have three sheets in my workbook. The first sheet is a list of options. The second sheet helps calculate those options and the third sheet is my table for vlookup

User
25/09/2018 - 02:22

If the options on sheet one are populated then I need a cell on my second sheet to populate with the whatever applys from my third sheet vlookup

Excelchat Expert
25/09/2018 - 02:24

Okay. I see you are giving an example on the sheet to your right. Once you are done let me know.

Excelchat Expert
25/09/2018 - 02:24

Thank you.

User

The $100 needs to only appear if the option on sheet one is available

User
25/09/2018 - 02:26

So If I remove the limits on sheet one then this $100 needs to be blank

Excelchat Expert
25/09/2018 - 02:28

Which option are you referring in sheet1 to be available?

User
25/09/2018 - 02:29

The ones I hightlight. If those were blank or less than zero, then I need the $100 to be balnk. If they are populated like they are then I need the vllokup to work

Excelchat Expert
25/09/2018 - 02:30

Where do you want to put the Lookup function?

User
25/09/2018 - 02:31

where the $100 is on the sheet

Excelchat Expert
25/09/2018 - 02:31

Okay.

Excelchat Expert
25/09/2018 - 02:32

I have renamed the sheets to reduce ambiguity.

User
25/09/2018 - 02:33

ok

Excelchat Expert
25/09/2018 - 02:33

I have renamed them to sheet1, sheet2 and sheet3

Excelchat Expert
25/09/2018 - 02:33

We can use those names to reference them.

User
25/09/2018 - 02:33

ok

Excelchat Expert
25/09/2018 - 02:34

I need to understand you correctly so that I can provide you with the CORRECT and best solution.

User
25/09/2018 - 02:34

ok

Excelchat Expert
25/09/2018 - 02:34

Which cell are we checking if is blank or not and then return the lookup function?

User
25/09/2018 - 02:34

Sheet 1 cell E2

Excelchat Expert
25/09/2018 - 02:35

Very good.

Excelchat Expert
25/09/2018 - 02:35

If it is populated, like now it has 500,000/500,000

Excelchat Expert
25/09/2018 - 02:36

What should we return in F5 of sheet2?

Excelchat Expert
25/09/2018 - 02:36

You can see that it's important in this case to move in one direction, either low to high, or high to low. This allows us to return a result whenever a test returns TRUE, because we know that the previous tests have returned FALSE.

User
25/09/2018 - 02:37

The vlookup table is on sheet three. I have added a state on sheet 1 so that we can use the vlookup properly

Excelchat Expert
25/09/2018 - 02:37

Sorry for that

Excelchat Expert
25/09/2018 - 02:37

The previous response was a typo error,,,please ignore it.

User
25/09/2018 - 02:37

ok

Excelchat Expert
25/09/2018 - 02:38

How can we know the state whose amount we want to return?

User
25/09/2018 - 02:40

It is working in my version

Excelchat Expert
25/09/2018 - 02:40

For example we return 100 in F5, how do we know it was 100?

User
25/09/2018 - 02:40

sheet 3

User
25/09/2018 - 02:41

Formula should have return 90 and did not

Excelchat Expert
25/09/2018 - 02:41

But I see now it is returning 90

Excelchat Expert
25/09/2018 - 02:41

Is that correct?

User
25/09/2018 - 02:42

Sorry it did. NOw if the options on sheet 1 were blank I need this to be blank as well. If the options are on sheet 1 like they are now I need it to populate that number

Excelchat Expert
25/09/2018 - 02:42

Okay.

Excelchat Expert
25/09/2018 - 02:43

In that case we will use the formula:

Excelchat Expert
25/09/2018 - 02:44

=IF(ISBLANK(Sheet1!$C$1),"",VLOOKUP(Sheet1!$C$1,Sheet3!$A:$B,2,False))

User
25/09/2018 - 02:44

If cell E2 was blank not C1

Excelchat Expert
25/09/2018 - 02:45

You mean, if cell E2 is blank C1 also to be blank?

User
25/09/2018 - 02:46

No cell C1 will stay constant. No change. The only cell that will change is on sheet 1 cell E2

User
25/09/2018 - 02:47

E2 will either show what you see now or be blank

Excelchat Expert
25/09/2018 - 02:48

So if C1 of sheet1 is blank, E2 of sheet1 should also be blank?

User
25/09/2018 - 02:48

no

Excelchat Expert
25/09/2018 - 02:48

Okay. What Do you EXACTLY mean?

User
25/09/2018 - 02:48

C1 will NEVER be blank. E2 is the one that will change and the formula needs change based on that

Excelchat Expert
25/09/2018 - 02:49

Okay.

User
25/09/2018 - 02:49

If I remove 500,000/500,00 on sheet 1. I need cell F5 on sheet 2 to be blank

Excelchat Expert
25/09/2018 - 02:49

Okay.

Excelchat Expert
25/09/2018 - 02:50

I see this works:

Excelchat Expert
25/09/2018 - 02:50

=IF(ISBLANK(Sheet1!$E$2),"",VLOOKUP(Sheet1!$C$1,Sheet3!$A:$B,2,False))

Excelchat Expert
25/09/2018 - 02:51

I have removed E2, and now F5 is blank.

User
25/09/2018 - 02:51

It is backwards but I can see what you are doing

User
25/09/2018 - 02:52

If the 500,000/500,000 is deleted then the 90.00 should disappear also.

Excelchat Expert
25/09/2018 - 02:52

How do you want us to adjust it?

Excelchat Expert
25/09/2018 - 02:53

I see it does disappear.

Excelchat Expert
25/09/2018 - 02:53

Try it out with me.

Excelchat Expert
25/09/2018 - 02:53

Delete the 500,000/500,000

Excelchat Expert
25/09/2018 - 02:53

F5 is now blank, corrrect?

User
25/09/2018 - 02:54

No

Excelchat Expert
25/09/2018 - 02:54

When you delete 500,000/500,000, what is the value in F5?

User
25/09/2018 - 02:54

90.00

Excelchat Expert
25/09/2018 - 02:55

In my end it is blank.

User
25/09/2018 - 02:55

When I added the 500,000 back in the 90 went away

User
25/09/2018 - 02:56

It is not on my end. Wish I could do a screenshot. It is working backwards

Excelchat Expert
25/09/2018 - 02:56

Let me confirm.

25/09/2018 - 02:58

Does it behave the same way?

Excelchat Expert
25/09/2018 - 03:01

Are you there?

User
25/09/2018 - 03:01

No this one works correctly

User
25/09/2018 - 03:01

Thank you,

Excelchat Expert
25/09/2018 - 03:01

In fact it is the same formula.

Excelchat Expert
25/09/2018 - 03:01

I did not change anything.

Excelchat Expert
25/09/2018 - 03:01

Do you have any other questions or clarification you may need about this problem and the solution?
