AJAX problem - switch between pages

I have got a PHP script that displays several pages with fields. User can fill out fields on one page, than go to previous one, edit fields there than go back etc. There is no AJAX aspect to this, just plain old PHP on the server side. Your job will be to get it to work, based on my code Also, you will later be another component to the overall project that I will explain once you are done with this one and post it as separate project for you. In complexity it will be little different from this one. E.g. it will involve adding DB support for logging in and saving half-done sessions. I will be ready to answer your questions immediately if needed via Skype (like if you don't understand the framework). I will work with you online at a time convenient for you. I do NOT (at present) have a database connected to this. You will have to store field values in a session object I am willing to pay well to the guy who is demonstrably smart and expert at what he is doing. I am also willing to consider hiring such a guy later on to work full time on bigger and better things. ## Deliverables 1) Complete and fully-functional working program(s) in executable form as well as complete source code of all work done. 2) Deliverables must be in ready-to-run condition, as follows (depending on the nature of the deliverables): a) For web sites or other server-side deliverables intended to only ever exist in one place in the Buyer's environment--Deliverables must be installed by the Seller in ready-to-run condition in the Buyer's environment. b) For all others including desktop software or software the buyer intends to distribute: A software installation package that will install the software in ready-to-run condition on the platform(s) specified in this bid request. 3) All deliverables will be considered "work made for hire" under U.S. Copyright law.
