Problem loading?

I am trying to figure out how to load a .txt file in to a dynamic text box. and I am using the Kirupa tutorial.
But for some reason my text files arent loading.
this is the code on the buttons ment to be linking the to newsBox but its not working :diss:

on (release) {
    loadText = new loadVars();
    loadText.onLoad = function(success) {
        if (success) {
            // trace(success);
            newsBox.html = true;
            newsBox.htmlText = this.myNews;

and here is what I have made so far
