Error al pasar datos de as3 a php/Mysql

[Pimager]

Código:

sendVars = new URLVariables;
sendVars.param1 = value1;
...
request_lv = new URLRequest("htttp://localhost/controlpanel.php");
request_lv.method = URLRequestMethod.POST;
request_lv.data = sendVars;
			
loader_lv = new URLLoader();
loader_lv.addEventListener(Event.COMPLETE, init);
loader_lv.load(request_lv);

private function init(e:Event):void
{
	var retVars:URLVariables = new URLVariables(e.target.data);
	trace(retVars);
}

Espero que te sirva
