Hi there!
User 12/04/2018 - 03:49
Hello
Excelchat Expert 12/04/2018 - 03:49
I'd love to help you with your SUM formula. Are you able to give me an example of the data you're working with?
User 12/04/2018 - 03:50
Yes, hold on and I'll copy it in
Excelchat Expert 12/04/2018 - 03:50
Fantastic - thanks
User 12/04/2018 - 03:51
Basically I need to sum B (hours) within the specified month (A) and separate it into the three different rental areas (C)
User 12/04/2018 - 03:51
I'll show you some of my past attempts
User 12/04/2018 - 03:52
F1 is not considering hall, however
Excelchat Expert 12/04/2018 - 03:52
ok sure thing. Just one question - what is the specified month going to be?
User 12/04/2018 - 03:53
In F1 it is January, but I will need to be able to copy this for all 12 months
User 12/04/2018 - 03:53
For which I can change the 1 to a 2, etc
Excelchat Expert 12/04/2018 - 03:54
Awesome that you used MONTH - very nice!
User 12/04/2018 - 03:54
I've also tried using SUMIFS but to no avail
User 12/04/2018 - 03:55
The criteria I've tried using for hall consists of "*upper*", "*lower*", "*kitchen*" and "*main*"
User 12/04/2018 - 03:57
F5 is an example of how I tried to incorporate the hall as a criteria as well
User 12/04/2018 - 04:00
I've also tried using SUM(INDEX(MATCH but since they INDEX and MATCH only return one result (unless 0 is in the column or row criteria) it doesn't actually end up summing anything
Excelchat Expert 12/04/2018 - 04:00
The F5 formula is so close I think..
User 12/04/2018 - 04:00
Yeah I can't quite get my finger on the problem though haha
User 12/04/2018 - 04:01
I tried ISODD as well instead of ISNUMBER
User 12/04/2018 - 04:01
and I tried TRUE and FALSE as the results
User 12/04/2018 - 04:03
Not sure if it helps to keep giving you wrong formulas but this was another attempt of mine before I tried MONTH (putting it in F6)
User 12/04/2018 - 04:05
This was extremely close, however it Excel defaults to the present year if it's not included, so any dates not in the current year don't work
User 12/04/2018 - 04:06
Oh, I didn't know this was a timed session. If we can't figure it out what will happen?
Excelchat Expert 12/04/2018 - 04:06
it can reset one more time!
User 12/04/2018 - 04:06
Okay excellent
Excelchat Expert 12/04/2018 - 04:07
if we can't solve, it can be reposted for sure
User 12/04/2018 - 04:07
Great, thanks
User 12/04/2018 - 04:10
My only problem with hard coding in those numbers in F6 is that it will not be transferable to future years (sorry i might not have specified this)
User 12/04/2018 - 04:10
Otherwise I could just hard code in the year in the date
Excelchat Expert 12/04/2018 - 04:11
right - gotcha that makes sense. I just wanted to get F6 working or to test it rather.. so that is working right there.. lets try and automate that part to be a single month entry like your initial formula
User 12/04/2018 - 04:13
Okay I almost deleted everything so I'll let you try and work it out, I'm still pretty stuck lol
Excelchat Expert 12/04/2018 - 04:19
hey!
Excelchat Expert 12/04/2018 - 04:19
check that out
User 12/04/2018 - 04:19
Hey that's nifty
Excelchat Expert 12/04/2018 - 04:19
COOL you can just change the month in cell J5!
User 12/04/2018 - 04:20
Would I be able to change the J5 reference to something like "*upper*"?
Excelchat Expert 12/04/2018 - 04:20
dont type the month in though
Excelchat Expert 12/04/2018 - 04:20
change the date actually in teh formula bar for that cell
Excelchat Expert 12/04/2018 - 04:20
Yes totally (J6 though)
User 12/04/2018 - 04:20
yes, sorry
Excelchat Expert 12/04/2018 - 04:20
Give this a test and let me know if this will work as a solution for you
Excelchat Expert 12/04/2018 - 04:21
and I'm SO sorry this took so long.
User 12/04/2018 - 04:21
Sure give me a second
User 12/04/2018 - 04:21
Thats ok!
User 12/04/2018 - 04:21
I know it's not an easy task
Excelchat Expert 12/04/2018 - 04:21
You really know your stuff...
User 12/04/2018 - 04:21
Thank you!
User 12/04/2018 - 04:23
Does the format of J5 need to be that way?
User 12/04/2018 - 04:24
I see in the formula bar it is 4/1/2017 but it displays April
Excelchat Expert 12/04/2018 - 04:24
I'm almost certain yes
Excelchat Expert 12/04/2018 - 04:24
"mmmm"
User 12/04/2018 - 04:24
How can Id o that?
User 12/04/2018 - 04:24
TEXT(J5, "mmmm")?
Excelchat Expert 12/04/2018 - 04:24
J5 is already in mmmm
User 12/04/2018 - 04:24
How can I do that on my sheet?
Excelchat Expert 12/04/2018 - 04:25
do you mean make a cell the "mmmm" format?
User 12/04/2018 - 04:25
Yes
Excelchat Expert 12/04/2018 - 04:25
go to format cell
Excelchat Expert 12/04/2018 - 04:25
then
Excelchat Expert 12/04/2018 - 04:25
from the Number tab, select custom
Excelchat Expert 12/04/2018 - 04:26
and then manually key mmmm as the format
User 12/04/2018 - 04:26
oh lol got it
Excelchat Expert 12/04/2018 - 04:26
Oh perfect
Excelchat Expert 12/04/2018 - 04:27
EOMONTH is a cool function
User 12/04/2018 - 04:27
So this is kind of a bump in my road
User 12/04/2018 - 04:28
Also yes I never really looked at EOMONTH, good find
Excelchat Expert 12/04/2018 - 04:28
what is the bump?
User 12/04/2018 - 04:28
but basically, the information I have pasted here is taken directly from a program that imports information from my Google Calendar
User 12/04/2018 - 04:28
so the format is mostly non-negotiable
User 12/04/2018 - 04:28
however...
User 12/04/2018 - 04:29
It formats the "hours" column in a hh:mm:ss format
User 12/04/2018 - 04:29
so when I apply our new formula, my result is
User 12/04/2018 - 04:29
1944:00
Excelchat Expert 12/04/2018 - 04:29
hmmm i see
Excelchat Expert 12/04/2018 - 04:29
one sec...
Excelchat Expert 12/04/2018 - 04:31
is the answer 81 hours by chance?
User 12/04/2018 - 04:31
I believe so, yes
User 12/04/2018 - 04:31
Before we had "30" in the "just in case" it was 81
Excelchat Expert 12/04/2018 - 04:32
cool... yes
Excelchat Expert 12/04/2018 - 04:32
so the cell that you have the formula in...
Excelchat Expert 12/04/2018 - 04:32
are you able to change the format of the cell that has the formula in it which brings back 1944:00?
User 12/04/2018 - 04:33
Yes! What do you think it should be?
Excelchat Expert 12/04/2018 - 04:33
number
User 12/04/2018 - 04:33
I'd like it to just be a plain old number like 81
User 12/04/2018 - 04:33
Okay awesome
Excelchat Expert 12/04/2018 - 04:33
see if it works
User 12/04/2018 - 04:33
perfect
User 12/04/2018 - 04:33
81
Excelchat Expert 12/04/2018 - 04:33
Yes!
User 12/04/2018 - 04:34
Let me try to implement this again
Excelchat Expert 12/04/2018 - 04:34
Please do
User 12/04/2018 - 04:36
Okay, so!
User 12/04/2018 - 04:36
Since the format for the date reference includes the year, I have the same problem that doesnt let me apply this to future years
Excelchat Expert 12/04/2018 - 04:38
hmmm
Excelchat Expert 12/04/2018 - 04:38
might have to add another element to the formula... that references the cell below J5
Excelchat Expert 12/04/2018 - 04:38
so you'd enter the month and the year
Excelchat Expert 12/04/2018 - 04:38
lemme see
Excelchat Expert 12/04/2018 - 04:38
like just another criteria to the SUMIFS function
User 12/04/2018 - 04:39
Right I see, so I'd just have a new cell somewhere that would be the year
Excelchat Expert 12/04/2018 - 04:40
yep exactly
User 12/04/2018 - 04:40
and the months that require the future year would be the first cell +1
Excelchat Expert 12/04/2018 - 04:40
im just trying to figure out the syntax for that last criteria
User 12/04/2018 - 04:40
Thank you
Excelchat Expert 12/04/2018 - 04:40
well you would just enter in whatever year you need the count for
Excelchat Expert 12/04/2018 - 04:45
ah i think i found it
User 12/04/2018 - 04:48
I'll copy this down in case the session ends
Excelchat Expert 12/04/2018 - 04:48
can you extend it at all or did we run out?
Excelchat Expert 12/04/2018 - 04:48
it's SO close
User 12/04/2018 - 04:48
I can't unfortunately!
User 12/04/2018 - 04:48
I will see what I can do from here
User 12/04/2018 - 04:49
thank you so much for your help
User 12/04/2018 - 04:49
It's a good start for sure
Excelchat Expert 12/04/2018 - 04:49
i wish I could've finished it!!!
User 12/04/2018 - 04:49
