I sell fabric by the 1/2 meter and by the meter using the attributes controller. I have quantity discounts controlling purchases of 2 meters or more, however if the user tried to purchase 2x 1/2 meters (using the drop down selection created in the attribute controller) this also qualifies them for the discount, which I don't want.
Does anyone know how I can put a maximum that any customer is allowed to purchase of a particular attribute. I tried using the price controller, but that controls the whole item not the attributes.
