Problem Loading Text from External Sources (?)

there is probably a very simple explaination for this but i am pretty new to flash and actionscript so here it goes…

i used this tutorial ( http://www.kirupa.com/developer/mx/multiple_dynamictext.htm ) to load text from an external source but am getting an error,

the button i am using also needs to load a picture (some code which i got from another thread on these forums) so maybe there a conflict with the code?

heres the code i am using for the button

 
on (release) {
 containerMC.loadPic("[http://webzoom.freewebs.com/pappageorgas/posterFull.jpg](http://webzoom.freewebs.com/pappageorgas/posterFull.jpg)");
 }
on (release) {
	loadText = new loadVars();
	loadText.load("text1.txt");
	loadText.onLoad = function(success) {
		if (success) {
			// trace(success);
			imageInfo.html = true;
			imageInfo.htmlText = this.mytext;
		}
	};
}
 

and here is the error i recieve

Warning Scene=Scene 1, layer=buttons, frame=1:Line 6: Case-insensitive identifier ‘loadVars’ will obscure built-in object ‘LoadVars’.
loadText = new loadVars();

Total ActionScript Errors: 1 Reported Errors: 1

anyone have any ideas???
thanks!
