Tweener looping problem

[COLOR=black][FONT=Arial]I’ve made a ticker that loads the text into a dynamic text box and all i want it to do is tween from right to left (distant based on textbox size) and then repeat. I have everything working except I don’t know how to make it repeat. I think there’s a looping porperty but not sure how to use it. I think it’s something to do with the fact that it’s inside a load function but I can’t seem to get the textbox size outside that function. Someone please help I’m sure it easy when u know how.[/FONT][/COLOR]

[COLOR=black][FONT=Arial]This is my code:[/FONT][/COLOR]
[COLOR=black][FONT=Arial] [/FONT][/COLOR]
[COLOR=black][FONT=Arial]var URL = “www…”;
ticker = new LoadVars();
ticker.onLoad = function(success) {
if (success) {
var text = this.text;[/FONT][/COLOR]
[COLOR=black][FONT=Arial] [/FONT][/COLOR]
[COLOR=black][FONT=Arial]//inputs text and resize the textfield so it fix[/FONT][/COLOR]
[COLOR=black][FONT=Arial] _root.bar_mc.TickerMC.TickerTextMC.ticker_txt.text = this.text;
_root.bar_mc.TickerMC.TickerTextMC.ticker_txt.autoSize = true;

[/FONT][/COLOR]
[COLOR=black][FONT=Arial] //find out how wide the textbox is and move it that fair past the endpoint
var textBoxW = _root.bar_mc.TickerMC.TickerTextMC.ticker_txt.textWidth; [/FONT][/COLOR]
[COLOR=black][FONT=Arial]_global.textEnd_x = Number((286.1+textBoxW)*-1); [/FONT][/COLOR]
[COLOR=black][FONT=Arial] [/FONT][/COLOR]
[COLOR=black][FONT=Arial]//move text from right to left and then place text back to the start point.
Tweener.addTween(_root.bar_mc.TickerMC.TickerTextMC,{_x:textEnd_x, time:2, delay:2, transition:“linear”, onComplete:function () {
_root.bar_mc.TickerMC.TickerTextMC._x=215;}
});
} else trace(“Ticker Error loading data”);
};[/FONT][/COLOR]
[COLOR=black][FONT=Arial]ticker.load(URL);[/FONT][/COLOR]
