sendAndLoad

Any ideas on why this does not work?...it should send and load Vars but it doesnt even trigger when complete...

thanks to any responders...

var postVars:URLVariables = new URLVariables();
postVars.userId='cat';
postVars.folderId='dog';
var request:URLRequest = new URLRequest();
request.url = "http://localhost/getSounds.php";
request.method = URLRequestMethod.POST;
request.data = postVars;

var loader:URLLoader = new URLLoader();
loader.dataFormat = URLLoaderDataFormat.VARIABLES;
loader.addEventListener(Event.COMPLETE, completeHandler);

loader.load(request);

function completeHandler(event:Event):void
{testerText.text='triggered';}
