I have a formula as below:
=SUM(K7)-AVERAGEIFS('2 TURN'!$K:$K,'2 TURN'!$F:$F,$F7,'2 TURN'!$G:$G,$G7)
The 2nd part of the formula returns an average figured which is subtracted from the figure in cell K7. Sometime the K column doesn't have a value but has N/A (not available). When this is the case, this formula returns a negative result = to the average in the 2nd part of the formula.
Is there a way I can have the formula return "N/A" is some non-numerical value when the cell in the K column (as per example, K7) has N/A ?
Many thanks
