NOOB Question! reuse scrollbar in other frame

1

Hi,

this is my first time building a website in as3. Still young and learning.
my problem:

my code in actionsscript 3 timeline scrollbar:

import fl.controls.ScrollBar;
import fl.events.ScrollEvent;

var mc: txt01MC = new txt01MC();
mc.x = 405,9
mc.y = 201

var mcMask:MovieMaskMC = new MovieMaskMC();
mcMask.x = mc.x;
mcMask.y = mc.y;
mc.mask = mcMask;

var sb:ScrollBar = new ScrollBar();
sb.x = mc.x + mc.width;
sb.y = mc.y;
sb.height = mcMask.height;
sb.enabled = true;
sb.setScrollProperties(mcMask.height, 0, (mc.height-mcMask.height));
sb.addEventListener(ScrollEvent.SCROLL, scrollMC);

this.addChild(mc);
this.addChild(mcMask);
this.addChild(sb);

function scrollMC(event:ScrollEvent):void{
mc.y = -event.position + mcMask.y;
}

Now I want it to use it on another frame, but first I need to delet the child (mc,mcMask,sb) right? how?
Than is it possible to use the same vars as above?

please help this noob!!!
