flv custom progress bar

:yikes: I am trying to reset the progress bar to 0 at each cuePoint. Basically what i am doing is using the playheadupdate and its taking the next cuepoint and subtracting the current to get the total cue time for each. This only works on the fist cuepoint and will not update after that the progress bar will keep growing if you dont set it back to zero.

Hopefully this makes sense to someone , im getting frustrated with it.
Thanks

Code:

---

import mx.video.*;
var flvPlayer:mx.video.FLVPlayback;
flvPlayer.pauseButton = pauseBtn;
flvPlayer.playButton = playBtn;
flvPlayer.backButton = backBtn;


function paramVal(cp:Object):Void{
//The paramNum is the parameter val with has the number(ex.1 , 2) for each cue
        var paramNum:Number = cp.info.parameters.val;

trace("Cue Number " + paramNum)
        flvPlayer.playheadUpdateInterval = 1;
        var listenerObject:Object = new Object();
        listenerObject.playheadUpdate = function(eventObject2:Object):Void {
playTime.text =  Math.round(eventObject2.playheadTime);
                var totalCueTime:Number = Math.round(flvPlayer.metadata.cuePoints[paramNum].time - flvPlayer.metadata.cuePoints[paramNum - 1].time);
                var playHead:Number = flvPlayer.playheadTime;
                var timeElapse:Number = flvPlayer.playheadTime - flvPlayer.metadata.cuePoints[paramNum -1].time;
                var pctLoaded:Number =  Math.round(timeElapse / totalCueTime * 100);

                        progress_mc.barMc._xscale = pctLoaded;
                        perCent.text = pctLoaded + " %";
                        if(pctLoaded >= 100){
                                progress_mc.barMc._xscale = 0;
                                }
                               
        }


flvPlayer.addEventListener("playheadUpdate", listenerObject);
}
flvPlayer.addEventListener("cuePoint",paramVal);
