126071 ajax form

I need someone to complete this form: [login to view URL] so that the user can add rows as needed. The autocomplete needs to work for all productID form fields and for the ones added. When a user selects an product ID, the product name and product price should also be displayed in the row between the ID an quantity text boxes. The css also needs to be corrected so that the autocomplete component shows up over the text fields. All you have to do is the ajax part of the form. I have already setup all the necassary php scripts and their is an API which will return XML. The winner of this project, if a good job is performed and the price is right, will get more work. This is for a larger app that will need to be completed ASAP and will heavily rely on ajax.
