Yes. I am able to choose piece or set from the drop down menu, but the number to the left stays at $12 because it is a cross reference to a value in bullet point number 2, which is also $12. What I was looking for is to have the value in the last line change to $$3.00 ($12 cost divided by 4 pieces in the set) if I changed the adjoining combo box to piece instead of set. I hope that makes sense.
