Cold Fusion Ajax Java Cart Revision

I have a current Cold Fusion shopping cart connected to MS SQL db: [login to view URL] I want the right hand column to display the items added and keep a running total without the page refreshing. Once user enters the quantity in the 'Qty' box, the item name and qty should display in the right column and should also display the total all the items in the list. I believe it requires Ajax or Java. There are 4 pages requiring this work. Breakfast, Vegetables, Entrees, Snacks
