Each week a total is calculated for the week just passed. Each 8th row is reserved for subtotals.
What I need is to have the 8th row make a subtotal each time. What i need should result in the following logic:
'=IF(MOD(ROW()-1,8),C9,SUM(D2:D8))
'=IF(MOD(ROW()-1,8),C10,SUM(#REF!))
How do i get the sum range to look at the 7 preceding rows each time?
