You need to test the results!

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

This formula needs to be entered as an array, although you will get a result
if you don't it is very likely incorrect - it will be off by 2 in most cases,
with a large data set you won't notice that, but.... However, if you enter
it as an array in 2003 you it will return a #NUM! error because you are
referencing the entire column. In 2007 that won't happen.

Also, this formula may return a #VALUE! error if the entry in A5 is numeric
and some of the entries in C:C are text.

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

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.
