Variable Hyperlink

I have a button that reads:

on (release) {
getURL(“http://somedomain.com/?submit_domain=register&domain="+domain_txt+"&tld_extension="+ext+"&submit=Lookup+Domain+>>”, “_blank”, “POST”);
}

I have a box that has the instance name of “domain_txt” and a selectable component box of the instance name “ext”

All of these three things are on different layers. When the window opens in a new window, the bar at the top says like:

_level0.instance5.domain_txt

Any idea?

The window popups into a pph file which takes the POSTEd data and puts it into a text box…

Thanks guys.

Basically looking for a tut or some info on variable hyperlinks
