I have a spreadsheet that has duplicate values for a series of items
throughout an engineering bill of material. I need to calculate total
demand.

Col Item qty
a b
12 5001 2,000
215 5001 1,005
367 5001 6,000

My total Demand for item 2001 is 9,005ea. How can I develp a formula to
help
me pull all of the duplicates out and add the total demand?

Thank you,
