Hi,

Didn't test, try this instead:

=SUMPRODUCT(--(IF(A1:A5A7:A11,A1:A5,A7:A11)-A13:A170),--IF(A1:A5A7:A11,A1:A5,A7:A11)-A13:A17)

Array entered. I don't know if this is the result you want but with dummy
data I get a result.

Cheers,

Hi,

You might consider an SUMPRODUCT function such as:

=SUMPRODUCT(--(IF(A1:A5A7:A11,A1:A5,A7:A11)-A13:A170),--(A1:A5A7:A11,A1:Â*A5,A7:A11)-A13:A17))

If this helps, please click the Yes button

Hi Shane

I tried your suggestion, but it just gives a #VALUE error (even if i
press Ctrl Shift Enter to make it an array formula)
