I'm trying to come up with a macro, but i'm having some
trouble.

I have 3 columns in sheet "ChopList" and 3 columns in
sheet "CALC4". I need the macro to look at columns F, H,
and J on sheet "ChopList" and find the row in which the
cell values are the same in columns B,C, and D on
sheet "CALC4" and copy the value of the last populated
cell of that row to Column L of sheet "ChopList" in the
row with the same values.

Pretty difficult for me to explain, if you need more info
let me know.

Thanks very much in advance for any input.
