Take information in one cell such as c6 that has 12 hrs in it and add another cell such as c25 to show any number greater than 8 hrs and to include a range of multiple cells such as c6-c23. The sum in that cell cannot equal a negative number. Example; if c6 had a sum of 6hrs the sum of c25 cannot equal -2, only 0. So if an employee had 12 hrs in cell c6 then c25 would equal 4 hrs of overtime. The cell range for c25 has to cover multiple cells (jobs) such as c6-through c25. Now from the same cell c6 that has 12 hrs in it add another cell such as q26 to show any number less than or equal to 8 hrs and to cover multiple cells (days). Example; an employee has 10 hrs monday through friday (cells c6, d6, e6, f6, g6) so cell q26 should show only 40 hrs and the other 10 hrs move into cell c26-2hrs, d27-2hrs, e28-2hrs, f29-2hrs, g30-2hrs to represent overtime for each day. Hopefully this helps, let me know if i need to explain further.
