help with set expression please

[#1]

This set function is supposed to sum price*Qty for current Financial Week's (FWeek). FWeek is a field in a list Box That can filter more than one week. the set Calc works when filtered to current week but not more than 1 Week.

How does it need to change to sum up ALL selected Weeks ?

sum({1<FWeek = {$(=FWeek)} } >} (PLU_PRICE*QUANTITY))
