I have a range of numbers, A10:L10, which represents headcounts during
the month. These numbers are a formula, not a manual input. If the
month has not occurred yet, the number equals 0. I want to add a
formula telling me my average headcount per month. However, because
the 0's are included, my average is always understated. Is there a way
to calculate the average while ignoring the 0's? I know I can do it by
deleting the 0's, but since it is a formula, I prefer not doing that.
