Try this:
=SUMPRODUCT(--ISNUMBER(A1:A20))

I am using COUNTA(a1:a20) formula. The colum that it is counting also
contains formulas. Some of the cell formulas are returning 0. Can I change
the cell formulas to return a blank cell or nothing so that my COUNTA formula
does not include that cell in its count?
COUNTA(a1:a20)

a2=a1, a3=a2
