Loading text from external sources

Hi guys, have a problem with a tutorial, loading text from external sources: http://www.kirupa.com/developer/mx/multiple_dynamictext.htm
Even if download the .fla file this is what i get when i run the file:

Warning Scene=Scene 1, layer=content, frame=1:Line 2: Case-insensitive identifier ‘loadVars’ will obscure built-in object ‘LoadVars’.
loadText = new loadVars();

Total ActionScript Errors: 3 Reported Errors: 3
(it repeat itself 3 times)

Why is this? Someone has good tutorial on this?
