OK. I want to set up attribites for a customer to order canvas prints. I want the total price to be determined by the square footage of the attributes. For instance, a customer chooses 30" x 40". 30" SIDE is one attribute and 40" SIDE is the other. That is rounded to 8.25 Sq feet. At $5/Sq Foot that comes to a total of $41.25.
Can someone suggest how this could be implimented? I can see that the attibutes controller is quite advanced. I just need a push and some suggestions from the pros here on this one.
Thanks for your time
