The formula I want to use is
=sumproduct(E3:E24, H3:H24)
but the problem is that both columns contain #VALUE!
errors in various rows. (In particular: if an error appears in E14, it will appear in all cells across E14:H14.)
How do I modify the formula so that it returns the SUMPRODUCT
of only the numeric values.
Here's a screenshot of the range I'm working with:
