excellent to know Jason, thanks.
Actually, I just tried setting the name fields to NOT be unique. So now it DOES replace the variation and calculates the discount.
So all I should have to do is give instructions to fill in both name fields if you are adding a qty of 2.
If they forget, i still have their contact info in the orders table, and could easily give them a call.
I think that will work for now. But i will keep in mind your support offerings.
