Loading URL encoded Variables [error]

programming flash

Hi,

I read this tips:

write in my way


stop();
var loader:URLLoader = new URLLoader();
loader.dataFormat = URLLoaderDataFormat.VARIABLES;
loader.load(new URLRequest("test/links/getVideo.txt"));
loader.addEventListener(Event.COMPLETE, sendAndGetVars);


function sendAndGetVars(Void):void {
    trace(loader.data is URLVariables);
}
//FLVurl

but get:

**Error #2101: The String passed to URLVariables.decode() must be a URL-encoded query string containing name/value pairs.
**
Why?
