I was wondering if this was possible :

I have a dropdown menu inside a form in Coldfusion. Is there a way to update page information based on what the user clicks.

So.. if the user selects a certain type of shipping, can I then update a price variable that is on the screen immediately, or does this have to be done with Javascript. Basically, what I am looking for is a listener function for when the user chooses an item from the drop down menu.

yes, that is done with javascript, without a form submission to the server

(that's how "ajax" works)

maybe ask in the javascript forum?
