Textfield url

1

I have a textfield that i want to pass the name of a swf file to be loaded. Its working when i put the name of the file in the URLRequest(“walk.swf”).
but when i try and pass it like this:


trace(textf.input.text); // walk.swf
var theUrl:String = textf.input.text;
var mRequest:URLRequest = new URLRequest(theUrl);

i get :
[COLOR=#ff0000]Error #2044: Unhandled IOErrorEvent:. text=Error #2035: URL Not Found.
[/COLOR]i cast it as a string. what am i missing here?

        function displayKey(keyEvent:KeyboardEvent) {
            if(keyEvent.charCode == 13){
               loader2 = new Loader();
                loader2.contentLoaderInfo.addEventListener(Event.COMPLETE, onCompleteHandler);
                trace(textf.input.text); // walk.swf
                var theUrl:String = textf.input.text;
                var mRequest:URLRequest = new URLRequest(theUrl);
                loader2.load(mRequest); 
            }
        }

function onCompleteHandler(loadEvent:Event){
var mc2 = loadEvent.currentTarget.content.getChildAt(0);
            addChild(mc2);
        }

help much appreciated.
