How do PS3 Advanced Options update Price?
I am not using the original code for shipping. Instead, I have modified PS3 to successfully include zoned (two shipping zones) shipping costs as a function of zip code. The shipping costs display fine for all products without options after a zip code is entered, and for products with their default options showing. I would like the shipping costs to update (like the price does) on the Products Display page when a non-default option is selected. Right now they do not change from the default values. Note too that the shipping costs that I have displayed in the cart are correct, regardless of options selected, so that part is working fine.
How does Price update as a function of option on the Products Detail page. I would like to duplicate that functionality for my shipping costs. At this point in the buying process, both zone costs are being displayed since the zip code is entered after an item is added to the cart.
