Hello again Kristine,
If you have to only accumulate the time in lieu if the hours for a given week are more than 30 the if the data is laid out
Day1, day2, day3,etc, Week total, Day1,day2,day3,etc,Week total etc
then the following formula would work.
=SUMPRODUCT(((Bxx:Zxx)>=30),Bxx:Zxx)/30 would give you a result.
As I said before what you might want could end up being quite complicated.
Harry
