Try this:

=SUMPRODUCT((A1:A4000=0)*(B1:B40000))

Hope this helps.

Any ideas on how I might compare two columns based on a conditional formula,
then count the number of occurences?
Col 1 - 0
Col 2 - 6
Number of rows in worksheet: *4000+

I'd like to be able to conditionally account for any value in col 1 that is
0 and has a positive number in col 2 (I don't need to report the number in
col 2). *I'd then like to have a count for the number of times this condition
occured.

Thanks for any help!
