Try...

=SUMPRODUCT((I1:I18={"GTB1","LOB1"})*(J1:J18=0))

or

=SUMPRODUCT(--(ISNUMBER(MATCH(I1:I18,{"GTB1","LOB1"},0))),--(J1:J18=0))

Hope this helps!

Ive used this formula successfully

What I would like to do is look for €œGTB1€� and €œLOB1€� in column I
I tried
=SUMPRODUCT(--(I1:I18={"GTB1","LOB1"}),--(J1:J18=0))

But it didnt work, it returned #value!
Thanks for your help.
