how to make slider control nested movieclips?

[warrenEBB]

I'm using AS3, CS5.5, on Windows764bit.

I created an animation with many different layers (and nested movieclips) on the stage, then wrote a short bit of As3 to add a slider control of the playback.

The problem/mystery is that when I change the slider, the nested MCs act strangely/independently.

Any advice on how to control everything at once?

here is the current file:

here is the code I added:

package {
import flash.display.*;
import fl.controls.*;
import fl.events.*;
import flash.text.*; //for TLF crap
    
 public class SliderClip extends MovieClip {
  var slider:Slider;
        
    public function SliderClip() {
    var tf:TextFormat = new TextFormat();
        tf.font = "Arial";
        tf.bold = true;
        txtBox2.defaultTextFormat = tf; 
        slider = new Slider();
        slider.setSize(200,0);      //set size of slider
        slider.move(50,700);        //position slider
        slider.liveDragging = true;     // control if slider updates instantly or after mouse is released
        slider.maximum = totalFrames;
        addChild(slider);
            slider.addEventListener(SliderEvent.THUMB_DRAG, slideHandler);
            slider.addEventListener(SliderEvent.THUMB_RELEASE, slideRelease);
            addEventListener(Event.ENTER_FRAME, slideFrame);
        }
    private function slideHandler(event:SliderEvent) {
        gotoAndStop(event.target.value);
        }
    private function slideRelease(event:SliderEvent) {
        play();
        }
    private function slideFrame(event:Event) { //moves slider to match current frame
        slider.value = currentFrame;
        if (slider.value == totalFrames){stop();}
        txtBox2.text = String(slider.value);
        }
    }
}

You probably have the MCs in individual frames controlled by the slider. Am I correct? Once the slider has reached a frame with an MC, this MC will play.
