I am using sumproduct to count a total number of cases. The formula I have
been using is:

=SUMPRODUCT((report!$Y$4:$Y$400<60)*(report!$Y$4:$ Y$400-60))

I have some cells that have a value of 0, and some are blank. I don't want
to count the cells that are blank, but I do want the cells with zero counted.

How would I do this?

Thanks in advance.
