Loading a text file into a dyanmic textbox


I followed that tutorial, it didn’t work and I followed one on macromedias website. Both are giving me the same error. I’m using flash mx 2004 professional version 7.2

Warning Scene=news, layer=actions, frame=1:Line 1: The identifier ‘loadVars’ will not resolve to built-in object ‘LoadVars’ at runtime.
loadVarsText = new loadVars();

Total ActionScript Errors: 1 Reported Errors: 1

It shopws me that and in the text box there all it says is ‘undefined’

The code on the layer that contains the textbox:

loadVarsText = new loadVars();
scroller.text = loadVarsText.var1;

I’ve also tried w/o that last line of code. Also the sample file off the kirupa tutorial gives me the same error. What’s going on?
