Navigating through slideshow

[aesthetics7]

I have two movieclips this is based off of. work_mc and workss_mc

Work_mc is a collection of thumbnails on one frame.

Workss_mc is a collection of larger images with descriptions that has to ability to scroll through each slide

The way you navigate this is you click in work_mc, whatever thumbnail you choose and it will open workss_mc.
Once you are inside of work_mc you can view the image, go back(which takes you back to work_mc) or you have prev and next

Workss_mc consistants of multiple frames and each frame has a different image on it.


Here is the code for a button in work_mc:

twentythreemographthmb_mc.addEventListener(MouseEvent.CLICK, clickHandler2);
twentythreemographthmb_mc.buttonMode=true;

function clickHandler2(event:MouseEvent):void {

     var workss_mc = new mc_workss();
     newClassRoot.showModalContent(workss_mc);
     workss_mc.x=225;
     workss_mc.y=200;
     workss_mc.gotoAndStop("twentythreemotion");
     workss_mc.addEventListener("closeButtonClick10", onCloseClick10);


}

function onCloseClick10(e:Event):void {
     var work_mc = new mc_work();
     newClassRoot.showModalContent(work_mc);
     work_mc.x=225;
     work_mc.y=130;
}

So this should go to twentythreemotion and stop, which it does and it works correctly.

However, once you are in workss_mc the prev and next button are not functioning properly.

If you click on the first thumbnail and start the show from the beginning: This is on frame 1 of workss_mc..

var a:Array=["urban","twentythree","citibrochure","csccard","rokroom","hiphop","metal","vangogh"];
var currentIndex:int=0;
worknextbtn_mc.addEventListener(MouseEvent.CLICK, worknextClicked);
function worknextClicked(event:MouseEvent) {
     currentIndex++;
     if (currentIndex>=a.length) {
          currentIndex=0;
     }
     gotoAndStop(a[currentIndex]);
}

workprevbtn_mc.addEventListener(MouseEvent.CLICK, workprevClicked);
function workprevClicked(event:MouseEvent) {
     currentIndex--;
     if (currentIndex>=a.length) {
          currentIndex=0;
     }
     gotoAndStop(a[currentIndex]);
}

This works correctly if I choose the first thumbnail that goes to frame one but if I choose another thumbnail on work_mc that will go to a different frame label in workss_mc the prev/next buttons won't function properly..
