In all Excel versions: =SUMPRODUCT(--(A1:A100="A"),--(B1:B100=2008))
Only in Excel 2007 : =SUMPRODUCT(--(A:A="A"),--(B:B=2008))
Only in Excel 2007: =COUNTIFS(A1:A100,"A",B1:B100,2008)

If I have 2 columns like below:
A,2008
A,2007
C,2007
B,2008
C,2007
A,2008
A,2008
B,2008
I can use COUNTIF(A1:A8,A11) to find the total occurance of A, but how
can I add one moe creterion so I can get the result that it's A and
also 2008 (2nd column). So the answer should be 3 in the example
above.
Thanks for the help,
liu
