I was able to resolve a #DIVIDE BY ZERO Error message by using this formula =IFERROR(COUNTIFS(I:I, 1, C:C, 1) / COUNT(Hinge:Hinge), 0).
However, I am currently hitting a road block on getting an accurate average from my sheet summaries.
Is there a way to get an average of all summaries not labeled OVERALL that will only count averages for summaries greater than 0?
