I have a spreadsheet of payment types for which I want to sum the tota
amount per type per month

A B C
Type Amount Month


I'm able to get the total amount per type by usin
=SUMIF(A:A,"TYPE",B:B), but can't work out how to get a total for eac
type each month

Somthing along these lines: =SUMIF((A:A,"TYPE",B:B)&C:C,"MONTH")) ????

Any idea's
