If column A and B are my data and I use the following formula to calculate
the hours of OT for each day =SUMIF($A$2:$A2,A2,B$2:B2)-8 to get the totals.
How do I get it to only give me the hours over 8 for each day and not the
totals.
With the above formula I am getting -1, 7, 10, -3, 7 I need to get the
totals as above.

Any suggestions
