=SUM(IF(FREQUENCY(IF(C:C=A5,D:D),D:D),1))

I assume you're using Excel 2007.

Try it like this:

=SUM(IF(FREQUENCY(IF((C:C=A5)*(E:E=5)*(F:F=4),D:D) ,D:D),1))

I'd use a smaller specific range if I were you! You're testing well over 3
million cells!

I'd like to apply some additional criteria to this unique value count.

=SUM(IF(FREQUENCY(IF(C:C=A5,D:D),D:D),1))

The array formula works ok without additional criteria. However, I'd also
like to include the rows where cells in E:E equal 5 and F:F equal 4. I've
done a SUMPRODUCT that would determine that without determining the unique
values, but I want to somehow combine the two.

Any ideas.
