You'll need several report variables. One would have to keep the group expression, and be initialized to some impossible value. The other one would be .t. if this one is different from the group expression (signal of new group). Third one would keep the group totals of the hours added only when the second one is .t. (something like iif(rvGroupHasChanged, RoundedPersonsSalary, 0), summing (calculate=sum, initial=0). In the summary of the report, print this third variable.

This is tricky to do, and it's specially tricky to take care of order of creation of these variables, but it's feasible. I know I've done one like that lately, and eventually got it to work after few retries.
