I am using the GOOGLE CHECKOUT MODULE as one of my payment options FOR X-CART payment module. I have a shipping plugin that tabulates shipping based on weight, number of items, etc. It transfers the shipping costs fine to paypal if that is selected, and money order if that is selected, but with google checkout does not, I think I have the option to have a standard shipping cost but really I need the real shipping cost transferred through because some items are much heavier than others and thus have all different shipping prices. It displays the shipping cost on the checkout page on my site, but need this transferring through to google.
Please only apply if you know for sure you can do this for me.
