I've seen similar threads here but can't seem to get them to work...here is
my situation.

spreadsheet 1
col A col B col C
FDP cpu 1
INS tape 2
FSI disk 3
FSI cpu 4
FSI disk 5

I need the answer to this question--If Col A = FSI AND Col B = disk, sum
column C. In this case, I expect 8 to be returned. I will be posting the
formula in spreadsheet 2, if that is important.

Please help!!
