AJAX and DHTML additions for cart

THIS PROJECT IS FOR RMASH ONLY I have already discussed all project details with RMASH and will be selecting him as the service provider. As such, there is not a need for you to bid at this time. The project involves adding some AJAX and DHTML scripting to an existing shopping cart interface that I am currently developing, allowing for streamlined updates of quantaties and options. There are three separate projects combined into this one, and RMASH will be providing all sections.
