Cannot load text into dynamic text box! HELP!

I am currently using this code…

loadText = new LoadVars();
loadText.load("info.txt");
loadText.onLoad = function(success) {
	if (success) {
		// trace(success);
		titleTxt.html = true;
		titleTxt.htmlText = this.titleX;
		}
};

…but it doesn’t work! It just says undefined in the text box. The variable of the text box is declared as ‘titleTxt’ and the variable in the .txt file is ‘titleX’. I don’t understand! HELP!
