Hi I was able to follow the instructions for the pizza toppings video to add custom line items with costing rules so that I can let my client's customers create a custom picture frame and check out withe the modfications included in the price.

My only issue now user experience wise is that if they make a mistake after adding the item to cart, they will have to start from scratch again . . which is not so intuitive. .. is there anyway that I can let the user edit line item products that are already added to the cart?

Thanks!
