Loading external scrollable text file in MX2004

1

I’ve been doing this tutorial (http://www.kirupa.com/developer/mx/dynamic_scroller.htm[url=“http://www.kirupa.com/developer/mx/dynamic_scroller.htm)%20using”])
using the same actionscript:

loadText = new loadVars();
loadText.load(“kirupa.txt”);
//creating the loadVarsText function
loadText.onLoad = function() {
scroller.text = this.kirupatext;
};

but I’m using Flash MX 2004 Pro and when I test my movie it gives me the error of

Warning Scene=Scene 1, layer=Layer 1, frame=1:Line 1: The identifier ‘loadVars’ will not resolve to built-in object ‘LoadVars’ at runtime.
loadText = new loadVars();
Total ActionScript Errors: 1 Reported Errors: 1

loadText = new loadVars();
loadText.load(“kirupa.txt”);
//creating the loadVarsText function
loadText.onLoad = function() {
scroller.text = this.kirupatext;
};

Basically i need to make a scrollable text box that load external txt file
anyone can help pls?
thx in advance
