I am looking for something like this:
http://www.codemashups.com/source/jquery/jquery-autocomplete-p1/ I need the user to be able to enter a product description then they can select the right one in the drop down box. Then it fills in the rest of the form jumps to the number needed the user enters that presses enter and you can then add more items. Then it should need to return a current total cost with and with out VAT and such. Then when the user it done to enter the ID's of the products in a comma separated value list into a MySQL database along with the total cost.
