The following formula returns an error as indicated with a green corner tab:
=IF(AVERAGE(C448:E448) >$P$2,1,0)
The cells I wish to use in calculating average are in cells C448, D448, E448.
Why do I have an error?
Note: If I change the formula to include cells A448 and B448 the green tab goes away. But, cells A448 and B448 do not contain data that would apply to the average calculation.
