Dynamically Loading Select Boxes ?

Is there a way of using event onChange to reload several select boxes ?

I have a two tables. One tables holds a tool list the other tables holds the ID of the tool list and make, model and serial no.

When they select a tool, I would dynamically like to load the other select boxes with Make, Model and Serial No but I can’t find a way to call or load the connector after the init() of the form.

Is it possible to use .getSelect(“name”) and .loadXML("php/data.php) within the event ?

I change the select to combo as the select does not have the method and all works now.
