Replace your minus signs,
=SUM(G31-G99)/COUNTA(G31-G99)
with colons:
=SUM(G31:G99)/COUNTA(G31:G99)

Many thanks for the reply. I am affraid that this formula did not produce
the result for me. I have these entries in line 31-34 Col. G:-
40.66
35.97
38.86
38.88
the average should be 38.59, but with the formula:- =Sum (G31-G99)/COUNTA
(G31-G99) I am getting 40.66 - the first entry. Where did I go wrong?
