I have a form where numeric values are selected from combo boxes. The values 0-4 may be chosen and an alpah character of "X" if none of the numerics are valid. I need to take these values add them up and average them. I want to ignore the fields containing "X" and also not use a field containing "X" in my average euquation (so if out of 16 fields I have 2 with "X" I only divide the sum by 14). Any ideas on how this may be accomplished? Zorro
