XML random quote rotator help

Hi,

I’ve been messing around with this XML random quote rotators from this site but I’m unable to make it so it doesn’t repeat the same quote twice. It has a tendency to show the same quote 3x in a row.


//importing tween classes
import fl.transitions.Tween;
import fl.transitions.easing.*;

//we create a variable to store the loaded XML
var xml:XML;
//the path to the xml file
var xmlPath:String = "data/quotes.xml";
//we create a loader and when the loading is over we call the xmlComplete function
var loader:URLLoader = new URLLoader();
//a url request for our loader
var req:URLRequest = new URLRequest(xmlPath);
loader.addEventListener(Event.COMPLETE, xmlComplete);
loader.load(req);
//a variable for our tween
var myTween:Tween;
//we need to set a timer 
var timer:Timer = new Timer(5000);
timer.addEventListener(TimerEvent.TIMER, changeQuotes);
timer.start();

function xmlComplete(e:Event):void{
    xml = new XML(e.target.data);
    addQuotes();
    randomQuoteTween();
}

//we create arrays to store the quotes and the authors
var quotesArray:Array = new Array();
var authorsArray:Array = new Array();
//we need a random quote number 
var randomNumber:Number;

function addQuotes(){
    //we loop through the "quote" element of our XML 
    for each(var item:XML in xml.quotes.quote){
        //we fill the arrays with quotes and authors 
        quotesArray.push(item.content);
        authorsArray.push(item.author);
       
    }
}

function randomQuoteTween():void{
    //calculating the random number
    randomNumber = Math.round(Math.random() * (quotesArray.length - 1));
    //filling the text fields
    quoteMC.quoteTxt.text = quotesArray[randomNumber];
    authorMC.authorTxt.text = authorsArray[randomNumber];
    //creating tween effects
    myTween = new Tween(quoteMC, "alpha", Strong.easeOut, 0, 1, 3, true);
    myTween = new Tween(authorMC, "alpha", Strong.easeOut, 0, 1, 3, true);
}

function changeQuotes(e:TimerEvent){
    randomQuoteTween();
}

I figured it requires using shuffle, but I don’t know how to put it in this code. I’m fairly new at this and would appreciate any assistance.

Thanks
