you can use arrary formula (sum with if)

sum(if((col1="a")*(col2="b"),sum_range,0))

enter with cntl+shift+entter

I have a spreadsheet that has 13 columns the first column for an
identifier then 12 more columns one for each month. I can add a sum
column but my data is based on a query and the number of rows changes
constantly. Currently I am using
sumif(A:A,"criteria",B:B)+sumif(A:A,"criteria",:C: C)+and so on so that I
get all twelve months of data. Is there a better way to do a sumif that
sums up all columns of data as opposed to adding 12 sumifs?

Thanks
