I will probably never use the code you have created here. I just thought I should write and say Congratulations on your hard work and efforts! It’s good to see you were able to come to the solution you needed!
I will however bookmark this page, and if I ever hear anyone needs such a feature as you have created here, I shall tell them all about it!
If I buy it, will it work? I am using WordPress 2.1.2 and Beta 3.4.7. So far I have had nothing but trouble. When you add items to the cart, they don’t. The cart doesn’t update because items aren’t being added. What is going on? Im not using any other plugins (except one), just WordPress 2.1.2, the widgets plugin and wp-e-commerce.
