Loading an external variable into a ListBox

When I use the following Action Script to pull the variable ‘leaguename’, which has the value “flashtest”, from my ASP page and insert the value into my ListBox called ‘playerlist’, the text ‘_level0.leaguename’ is written in the ListBox instead of ‘flashtest’.

myData = new LoadVars();
myData.onLoad = function() {
leaguename.text = this.leaguename;
};
myData.load(“livedraftvar.asp”);

playerlist.addItem(leaguename);

The output from my ASP page is: &leaguename=flashtest&

What am I doing wrong? Everything looks right to me.
