# Thread: Array formulas

1. ## Array formulas

I am working on revamping my organization's expense report. I've been trying to figure a total based on two conditions. Here's an example of what I'm trying to accomplish: if a cell in the range of B6:B30=A and a cell in the range of F6:F30=520 then I want to add their totals, but only if they're in the same row. For instance if B8 has an A and F8 has 520, then I want whatever is in the row 8 total column added to all the other "A520"s. I searched Microsoft's website, figured out I needed to use an array formula, and found some samples. It seemed like the SUMIF function was what I should use. I tried these formulas and neither worked: {=SUM(IF((B6:B30="A")*(F6:F30="520"),G6:G30))}and {=SUM(IF((B6:B30="A")+(F6:F30="520"),G6:G30))}. Then I posted this question on a local helpnet, and someone suggested I try this: {=SUM(IF(B6:B30="A",IF(F6:F30="520",G6:G30)))}. That didn't work either. Does anyone have any suggestions as to what may be going wrong here? Any help would be greatly appreciated!

Thank you,
Amy

Hi Amy,
My first thought would be to check if your 520s are text or numbers. I think most of those formulas might work if you changed the ="520" bit to =520 (Excel won't equate the number five hundred and twenty with "520" if you see what I mean - one is text, the other is a number.)
Hope that helps.
PS I've assumed you aren't typing the curly braces in manually but rather are array-entering it - i.e. typing =SUM(IF(B6:B30="A",IF(F6:F30=520,G6:G30))) then pressing Control-Shift and Enter?

Rory is correct. Does the attached meet your requirements?
