Action Script Problem-HELP!

I have a link in a scrollbar using dynamic text and a.txt file. It works for a simple link like www.apple.com, but the link I want to use is a specific address at MapQuest.com:
E.g., http://www.mapquest.com/maps/map.adp?city=minneapolis&state=mn&address=3001+hennepin+ave.&zip=55408&country=us&zoom=4/
When I insert this URL, the link and all text after it no longer appear in the scrollbar. The characters in the URL are messing up the Action Script. Any way around this problen???
I’m AS challenged, so I’m at a real disadvantage here.
This is my AS for the scrollbar:

loadVarsText = new loadVars();
loadVarsText.load("info.txt");
loadVarsText.onLoad = function(success) {
	if (success) {
		trace;
		scroller.html = true;
		scroller.htmlText = this.var3
	} else {
		trace;
	}
};
