I am adding up scorecards and averaging sections, then coming up with a GC Total Average Score. Sometimes there are no score (blank). I would like those blanks to be changed to N/A and not calculate in the average score. Here is a screenshot of the several different average columns I am working on.
I would like a Pre-Construction Average (3 columns in orange), Construction Average (1 column in blue) and GC-Closeout Average (3 columns in purple). Then the GC Total Average Score to combine all 3 of these colored areas.
