I want to get a count based on three columns of data. In column A I have a
department code, in column B I have plan IDs, and in column C I have a flag
that indicates if this is a financial adjustment. I want to count all the
plan IDs by department code where it is NOT a financial adjustment(or
conversely, where it says "Current").

A B C
004 Plan1 Adj
004 Plan1 Current

After reading many of the posts on this forum, I've been trying to get
SUMPRODUCT to work. This is what I've written so far:

=SUMPRODUCT(--(A$13:A$15000="004"),--(B$13:B$15000="PLAN1"),--(C$13:C$15000="Current"))

I should get a count of 10, but it returns 0 not matter how I tweak it.
What am I doing wrong?
