Ajax/Selectbox/Loading 2 URL's

Hello! I got: 1x? select box, with the clients listed and the values representing the ID. 1x DIV containing the contactdata/address. 1x DIV containing orders. +? 2 perl scripts fetching the? requested data in the mysql table. What i need: I want the content of? two different DIVs to change as soon as a clients name? is selected in the? selectbox. Can someone help? This is an example, but instead of clicking I want it to happen as soon as name is selected in the dropdown. <[login to view URL]> To keep it simple I have removed some other textboxed that i will add again. The whole thing will be used to make sure that the right client is receiving the right order. :)
