Filter Formula Parameter Question to make report recurring:

I want it to recur every Thursday morning for the previous Monday through Sunday.  I keep trying to make the date formulas but they keep failing.  I have used

DateAdd(“d”,-10,today) and DateAdd(“d”,-4,today) as the formulas but that didn’t work for me, this is the original below before I changed anything.  Can you help?  The way I am doing it keeps failing.  Thanks!

 

(If {RV_PB_PAYROLL_BOARD.NAME} = "Filled"

    Then {RV_PB_PAYROLL_BOARD.START_DATE} <= {?End of Work Period}

    Else If {RV_PB_PAYROLL_BOARD.NAME} = "Closed"

        Then {RV_PB_PAYROLL_BOARD.ACTUAL_END_DATE} >= {?Start of Work Period} and {RV_PB_PAYROLL_BOARD.START_DATE} <= {?End of Work Period})
