Checking an external swf is loaded?

Question

Hi
I'm loading an external .swf via typing the swf name into an input text field and hitting a submit button.
The swf loads fine, but I'm trying to incorporate updating a status text field on a succesful load or if there is an error during loading.
I can't find my mistake in the code - to me it should be making  load_status_txt display "ok", but the swf just loads with no status update.
All the text fileds are fine, because if I code  load_status_txt.text = "hello" straight after addChild(loader); -  load_status_txt displays "hello"
Can anyone see an obvious mistake below?
Thanks so much again.

loadSwfBut.addEventListener("mouseDown", sendData)
function sendData(evt:Event){
    if(loadSwf.text !=""){
var Xpos:Number = 0;
var Ypos:Number = 100;
var swf:MovieClip;
var loader:Loader = new Loader();
var defaultSWF:URLRequest = new URLRequest(loadSwf.text);
loader.load(defaultSWF);
loader.x = Xpos;
loader.y = Ypos;
addChild(loader);
        loader.addEventListener(Event.COMPLETE, dataOnLoad);
    } else load_status_txt.text = "All fields are mandatory"
function dataOnLoad(evt:Event): void{
    load_status_txt.text = "ok";
stop();

use:
loadSwfBut.addEventListener("mouseDown", sendData)
function sendData(evt:Event){
    if(loadSwf.text !=""){
var Xpos:Number = 0;
var Ypos:Number = 100;
var swf:MovieClip;
var loader:Loader = new Loader();
var defaultSWF:URLRequest = new URLRequest(loadSwf.text);
loader.load(defaultSWF);
loader.x = Xpos;
loader.y = Ypos;
addChild(loader);
        loader.contentLoaderInfo.addEventListener(Event.COMPLETE, dataOnLoad);
    } else load_status_txt.text = "All fields are mandatory"
function dataOnLoad(evt:Event): void{
    load_status_txt.text = "ok";
stop();
