Dave,

Brilliant!

It was the #N/A in column F!

Sorted it, many thanks.

What formula did you use?

Do you have #n/a's in either of those two ranges?

Thanks Dave, but I'm getting #N/A and I can see there are some rows with this
info!

Can you offer any suggestion?

=sumproduct(--(left(f1:F100,3)="npt"),--(left(a1:a100,2)="pc"))

You can't use whole columns with this kind of formula.

Can someone assist me with a formula to sumproduct with wildcards, please?

=SUMPRODUCT(--(F:F="NPT*"),--(A:A="PC*"))

I've got this but it doesn't work!!
