=SUMPRODUCT(('13b'!A3:A75="Customer1")*('13b'!C3:C 75="QAR")*('13b'!H3:H7531)*('13b'!H3:H75<=93),('1 3b'!F3:F75))

Check whether the A3:A75 criteria is "Customer1" or "Customer 1". If it is
Customer 1 then change the A3:A75 criteria in the formula also. Since there
was an unfortunate Paragraph Mark in your post, so I could not able to
identify.
