=sumproduct((a2:a22="itemname")*(b2:b22=12)*(c2:c2 2=f1)*d2:d22)

Hello:

I have a list of inventory items. Column A has the Item, column B has the
Item Lot Number, column C has the Expiration Date, and column D has the
Quantity.

I want to subtotal the Quantity column for records that have the same
Item,
Item Lot Number, and Expiration Date. In other words, I need to subtotal
column D based on A,B, and C. I am using Excel 2003.
