I would like to have someone modify oscommerce so that a product can have following attributes:
1. Text field where custommer enters length of fabrick in cm.
2. Drop down selection for 2-3 different widths of fabrick eg. 400cm and 500cm.
When user enters these values a third field shows square meters(cm) and when the custommer goes to the shopping_cart it calculates the products price according to: length X widt X price of product.
