I am trying to determine the health of a task based on schedule variance.
If the schedule variance is:
'>0.9 green
'<0.8 red
between 0.8 and 0.9 yellow
=IFERROR(AVG(CHILDREN()), IF([Actual Completion Percentage %]@row = 1, "", IF(AND(Variance@row > 1, [Actual Completion Percentage %]@row < 1), 0), IF(AND(Variance@row > 1, [Actual Completion Percentage %]@row = 0), IF(TODAY() < [Baseline Start]@row, " ", IF([Schedule Variance]@row = 1, "")))))
