I want to have a table as such:

state population

CO 100
NE 200
CO 300

I want to count the number of times state is CO and Population is
200. In the example it should result in a count of 1.

How do i formulate this?

thanks.

Hi Geoff
Try this:

=SUMPRODUCT((A1:A3="CO")*(B1:B3200))

=SUMPRODUCT(--(A2:a100="CO"),--(B2:B100200))
