It might help alot if i simplify this as I can actually isolate my problem to the first subreport (B ). To date I have been unsuccessfuly in defining a variable in this subreport that can sum up all of the hours for each Employee group. For example, forget the fact that I would like to return this variable to a master report, let's say I would like to display it in the subreport summary, for example: Code: Employee 1 Total Hours: 8.00 7/1/07 Task 1 4.00 7/2/07 Task 2 4.00 Employee 2 Total Hours: 5.00 7/1/07 Task 3 3.00 7/2/07 Task 4 2.00 All Employee Hours: 13.00 How would i define the variable to display all employee hours (ie, calculation type, expression, evaluation time)? If i can get this right, it should be no problem to pass it up to the master report.
