I know this has been addressed, but I am still having trouble getting my sumproduct formula to work. I am using Excel 2003. In column a, I have order numbers that begin with 4 for stock orders and begin with 5 for custom orders. In column e, I have quantities. In column s, I have an "x" if the order has been assembled. I am trying to get a total for the number of custom assemblies that have been completed. The formula that I am using is listed below, but is returning a value of 0. Any help is appreciated!!
=SUMPRODUCT(('Current Workorder List'!A3:A100="5*")*('Current Workorder List'!S3:S100="x"),'Current Workorder List'!E3:E100)
=SUMPRODUCT(('Current Workorder List'!A3:A100="5*")*('Current Workorder List'!S3:S100="x"),'Current Workorder List'!E3:E100)
