Scrolling Dynamic Text - linking a url in the file

I have used the Scrolling Dynamic Text Tutorial and it works great. I have a url in the file that I want people to click on to launch within the movie. My problem is I can not figure out the code to do this.

Action Script code
loadText = new loadVars();
//creating the loadVarsText function
loadText.onLoad = function() {
scroller.text = this.leaguetext;

Any help would be appreciated.
