Simple text loading problem

I’ve followed the tutorials for loading text from an external source into a Flash MX 2004 file but when I test the following message appears and the text does not load.

"Warning Scene=Scene 1, layer=Layer 2, 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"

Does anyone know what I’ve done wrong or have there been changes to AS in 2004 that I’m missing?

The error message can give you some tips… watch out for the capital L
LoadVars
