I have multiple worksheets all using the same template I have a summary page and have a formula that works for an individual sheet
=SUMPRODUCT(--(sheet1!F4:sheet1!F500>=A1),--(sheet1!F4:sheet1!F500
the formula checks the relevant ranges on sheet 1 and returns the values in the boxes in the date range specified in A1 and A2
The problem is that I want to do this for multiple sheets and use a 3D reference.
I have tried
=SUMPRODUCT(--(sheet1:sheet3!F4:sheet1:sheet3!F500>=A1),--(sheet1:sheet3!F4:sheet1:sheet3!F500
and also thrown in some extra brackets to be safe
=SUMPRODUCT(--((sheet1:sheet3!F4):(sheet1:sheet3!F500>=A1)),--((sheet1:sheet3!F4):(sheet1:sheet3!F500)
neither of these work and I am getting the #NAME? error
any ideas would be appreciated
Thanx in advance
Gary
