SUMIFS with multiple sum range columns

I've tried looking at a bunch of forum posts but to no avail...

This is how the formula exists now:

=SUMIFS(Payback_Amount,Payback_Account,$A$21,Payback_Period,I$8,Payback_Fiscal_Year,I$7,Payback_Project,$B$4,Payback_Name,"*BLANK*")

But I want ADD another column in the sum range so that it functions like this:

=SUMIFS(Payback_Amount+HSV,Payback_Account,$A$21,Payback_Period,I$8,Payback_Fiscal_Year,I$7,Payback_Project,$B$4,Payback_Name,"*BLANK*")

Excel won't allow me to include two columns in the sum range. In looking at other posts it seems like something that sumproduct might be able to do, but I can't for the life of me figure out how. I DON'T want to do this:

=SUMIFS(Payback_Amount,Payback_Account,$A$21,Payback_Period,I$8,Payback_Fiscal_Year,I$7,Payback_Project,$B$4,Payback_Name,"*BLANK*")+SUMIFS(HSV,Payback_Account,$A$21,Payback_Period,I$8,Payback_Fiscal_Year,I$7,Payback_Project,$B$4,Payback_Name,"*BLANK*")

Any ideas??

Hi -

SUMPRODUCT will do what you want, basically as you suggest by adding the two columns together first and then applying your criteria like this SUMPRODUCT((A+B),CRITERIA1,CRTERIA2,...)

SUMPRODUCT is a little difficult to understand at first, but here is a great article that explains it really well and will open a lot of new doors for you as an excel user.

Good luck - hope this helps.
