Ajax Shopping Cart SEO Problem

I have SEO URLs contribution installed in my oscommerce shop, a developer from here wrote an ajax shopping cart for me. Part of the code for the ajax functin is in the [login to view URL] file. Unfortunately the code is braking the function of the SEO URLs. Im looking for someone to fix this just now please, I will pay $30 max to fix this. If you are placing a bid, you must start work right away please, its important to have this problem fixed due to the url that are index.
