How to alter width of movieclip in slider from parent

I have a slider component setup in my flash app. This slider has a few extra movieclips that I have created.

From the parent timeline, I would like to change the width of one of those movieclips in my slider.

I can't just access the child movieclip like I usually would (slider_mc.other_mc.width) because it sits in a slider so it gives me this error:

ReferenceError: Error #1069: Property other_mc not found on fl.controls.Slider and there is no default value. at play_fla::MainTimeline/frame1()

Does anyone know how I could do this?

Thanks

EDIT:

Just to explain further:

the slider component is a movieclip with the instance name slider_mc and other_mc sits inside the slider movieclip. I need to alter other_mc's width from the parent movieclip.

Hope that helps.

You need to listen to events from the Slider. Something like this should work if both the slider and other mc are in the same timeline

import fl.events.SliderEvent;

slider_mc.addEventListener(SliderEvent.THUMB_DRAG, thumbDragHandler);

function thumbDragHandler(event:SliderEvent):void {
    other_mc.width = event.value;
}
