Loading Text From External Sources

I’ve done the tutorial ( http://www.kirupa.com/developer/mx/multiple_dynamictext.htm ), but now i want to do something a little different.

I have the text box that the external txt files are loaded into on the root timeline.

I however, want to have the buttons dynamically loaded in, which means they’re in an SWF that isn’t on the main timeline. (I’m loading the SWF into a holder on the root which has the buttons on it) I need to know what changes i have to make to make it work.

on (release) {
 	loadText = new loadVars();
 	loadText.load("TEXT1.txt");
 	loadText.onLoad = function(success) {
 		if (success) {
 			// trace(success);
 			newsBox.html = true;
 			newsBox.htmlText = this.myNews;
 		}
 	};
 }
