Not playing the same 2 random frame lables in a row

1

Hi everyone last time I left you I was working on having a slide show that jumps to random frames labels well I got that taken care off:


function getRandomLabel():String
{
    var labels:Array = new Array("a","b","c");
    var index:Number = Math.floor(Math.random() * labels.length);
    return labels[index];
}
this.gotoAndPlay(getRandomLabel());

But the plot thickens, now I’m trying to get the abvoid playing the same frame lable 2 times in a row. Here is the code I currently have:


var labels:Array = new Array("a","b","c","d","e","f");
var index:Number = Math.floor(Math.random() * labels.length);
var currentRandomLabel:String;
var newRandomLabel:String;
function getRandomLabel():String
{
 return labels[index];
}
function nextRandomFrame():void
{
 getRandomLabel();
 trace("Current random label: "  + currentRandomLabel);
 if(currentRandomLabel != newRandomLabel)
 {
   currentRandomLabel = newRandomLabel;
   trace("New Random Label: " + newRandomLabel);
   this.gotoAndPlay(getRandomLabel());
 }
 else
 {
   trace("I'm trying to find a new frame label!");
   nextRandomFrame();
 }
}

Now I’m looking this code over and to me it looks like it should be working. I simply have added a


var currentRandomLabel:String;
var newRandomLabel:String;

To the code and then compair them in a conditonal. What is actully happening is when I publish my movie it simply plays throught the time line linearly going from A to F in normal order.
If any one feels like looking over the FLA plz feel free to DL it at this link:
