I need to count the number of dates in column Y based on whether or not a
number is entered in column X. I've tried several varieties of the COUNT
functions and keep getting errors.

Here is scenario: if columnX contains "1" in any of the cells, I need the
function to count the number of dates in columnY that correspond to those
cells from columnX with the number 1.

Thanks,

For the specific number of 1 in column X:

=SUMPRODUCT(--(X1:X10=1),--(ISNUMBER(Y1:Y10)))

For *ANY* number in column X:

=SUMPRODUCT(--(ISNUMBER(X1:X10)),--(ISNUMBER(Y1:Y10)))

You'll need to use SUMPRODUCT, not COUNT, COUNTIF, or COUNTA for that task.

The COUNT functions work only on one set of criterias, not multiple sets
(same with SUMIF...)

Perfect solution ~ thanks so very much. This was my first time to use the
discussion posts and I'm definitely hooked on looking here first when I have
a problem.

Again, much appreciated.
