HiRob,
Why are you using AVERAGEIF?
Does this work:
All three columns contain the same formula in the footer row.
B11: =IF(SUM(B)<>0,AVERAGE(B),"")
Average ignores empty cells and cells containing text when summing a range of cells and when counting the number values in those cells. In column B, that would produce a count of zero values to average, and would produce a 'division by zero' error in A11. The IF statement avoids that by calculating the average only if the sum is not equal to zero.
The heading on column B was originally correct, as all body cells in this column were empty for the first test. Entering text in B8 was done after the initial test, and gave the sme result (shown)
Regards,
Barry
