Try this and put a date into cell C1 to compare
=SUMPRODUCT(--(A1:A100(C1)),--(B1:B1006))

Hi All

I have 2 columns: A has dates (appointment dates), B has integer numbers
(current waiting times in weeks).
I basically want to do:
COUNTIF A1:A20 30/06/2007 AND B1:B20 6
In other words, of those with appointments after 30 June 2007, how many have
already been waiting more than 6 weeks
?? Possible with one statement of the form:
=COUNTIF(AND(A1:A20,"30/06/2007",B1:B20,"6"))

Any help appreciated.
