If a person puts ANY combination of a shirt in the shopping cart, it works. After the item’s in the cart, the QUANTITY box changes to zero. Then, if someone wishes to add another variation of that same shirt, 99 times out of 100 they’ll miss the fact that the quantity has been changed to zero. They’ll get an error message: “Sorry! 0 Quanitity!”
