Dropdown boxes

Hi

I need to link three dropdown boxes together for an ecommerce website.

Basically the first box is the item manufacturer, the second lists all the models from that manufacturer and the third will list all the accessories available for that model.

The product information is contained in an access database.

Can anyone help or suggest a way of doing this? I have looked at various tuts online but none show how to do what I need.

Thanks

Ian

if you want the subsequent select lists to be populated after a selection without a page refresh then you will need to do it with AJAX

and what server side scripting language do you have on your server?
