combo box

I've been trying to learn how to use the combo box component, and was wondering how you post the selected item from the box to an external php file.

So basically, if the combo box has an instance name of my_cb, can I use an action on the submit button like:

on (release) {
getURL("search.php", "_self", "POST");
}

What is the correct way to get this to work?
