Dynamically Loading Text Troubles

Whenever I try to load text dynamically, I get this error:

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

Total ActionScript Errors: 1 Reported Errors: 1

It happened when I tried to make a dynamic text box, and then it also came up when I downloaded the source files for one of the tutorials here on kirupa. I’m not sure what’s up with it.
