Form 'POST' issues

Hey all - got a little issue with sending data from Form to a URL…

The URL as it stands to me looks like a ‘GET’ ? Can anyone shed some light on how I can get these fields to submit to this URL?

eg…

submitBtn.onRelease = function() {
myLoadVars = new LoadVars();
myRecVars = new LoadVars();
myLoadVars.last_name = last_name.text;
myLoadVars.first_name = first_name.text;
myLoadVars.mobile_phone = mobile_phone.text;
myLoadVars.email_address = email_address.text;
myLoadVars.ResidentialArea = ResidentialArea.text;
myLoadVars.sendAndLoad(“http://oi.vresp.com?fid=cff35b0b30”, myRecVars, “POST”);
myRecVars.onLoad = function() {
this.gotoandStop(2);
};
};
stop();
