I have a form with three list boxes, say make/model/year. I also have a few links to the side that are say new/used/private. I would like the user to click on one of the links (new/used/private) and have the first list box (make) change dynamically by reading from a database. Then after they select a make the second list box (model) changes by again reading from a database. How do I make this work? How do I have to set up the links on the side to accomodate these dynamic changes in the first place and how do I change the list boxes dynamically once selections are mde from them? Any help would be greatly appreciated.
