Hi

Try
=SUMPRODUCT((Sheet1!$A$2:$A$20=$A2)*(Sheet1!$B$2:$B$20=$B2))

Hi,

Try...

=SUMPRODUCT((Sheet1!$A$1:$A$20=Sheet2!A1)*(Sheet1!$B$1:$B$20=Sheet2!B1)*(Sheet1!$A$1:$A$20<>""))

Or, if you're not worried about blank cells being tested for, then
just...

=SUMPRODUCT((Sheet1!$A$1:$A$20=Sheet2!A1)*(Sheet1!$B$1:$B$20=Sheet2!B1))

would do.
