If the only error values would be #N/A..
try this regular formula:
=SUMIF(A1:A10,"<#N/A")/COUNT(A1:A10)

Adjust range references to suit your situation.

Is that something you can work with?

I am attempting to build a running daily score average report based on
several categories that either have a numeric or N/A value. How do I omit
the N/A values from the average? I can't seem to make it stop assigning a
zero value to those cells.
