I have done this in JavaScript - but I dont have any code handy. Basically you will need to pre-generate a series of JavaScript arrays for each category of product at the top of the web page. Then you have a JavaScript event handler in the category pulldown that changes the product pulldown to a different array whenever the category changes (use something like onClick or onChange or a similar relevant event). Works pretty well - I once worked on a project which pulled data from Access via ODBC (I was coding in ASP - bleh! Never again... ;-) and generated the web page with the arrays and JavaScript functions at the top to handle the switching of the pulldowns. -- Aj. Sys. Admin / Developer
