Help externally loading text!

I’m trying to do the tutorial on scrolling dynamicly loading text- easy enough…I don’t have a scrollBar component in the UI’s and when using the one from the open source tutroial it doesn’t snap to/resize to text box…then whne test movie I get Warning Scene=Scene 1, layer=text, 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

This is suposed to be easy…lame
