Loading text from external sources

hi, I’ve been trying to make a flash site, which when pressed on a button from a menu, loads text from external resources to a dynamic text box. first I used this tutorial, but I keep getting the error:

Warning Scene=Scene 1, layer=menu, frame=1:Line 2: The identifier ‘loadVars’ will not resolve to built-in object ‘LoadVars’ at runtime.
loadText = new loadVars();

Total ActionScript Errors: 1 Reported Errors: 1

I honoustly don’t even know what loadVars is, does and the one who wrote the tutorial didn’t either. anyway, the weird thing is that the source files I downloaded from the tutorial do work (but also give the same error), but mine only gives the error and does not load the text.

My aim is actually to get something like this:http://www.clusta.com/Flash2/clusta@_design_v4.html then look at the small box with the news. Just a simple textbox, which loads html/css/text from an external file (so that my friend, for whom I make this site, can update it himself(he knows flash even less then me)).

I hope anyone can help me out :b:
