How a SWF Child can control a Parent's function/variable ?

Question

For instance, in the below code a parent can control a SWF
child’s function “alert ()”.
But how a SWF child can control parent’s function
“ReceivingChildMsg()” ?

Hi clbeech
I simplified the code to simply get the swf child controlling
its parent variable tp ( textfield ) and its content.
I used your suggestion (parent.ReceivingChildMsg( ) and
root.ReceivingChildMsg( )) but I get an error message:
quote:
“1061: Call to a possibly undefined method
ReceivingChildMsg through a reference with static type
flash.display:DisplayObjectContainer.”
Here is the code:
package
import flash.display.MovieClip;
import flash.text.*;
import flash.events.*;
import flash.display.SimpleButton;
public class Child extends MovieClip
public function Child():void
btn.addEventListener(MouseEvent.CLICK,clickHandler);
public function clickHandler(event:MouseEvent):void
//root.ReceivingChildMsg( "Received Child Message");
parent.ReceivingChildMsg( "Received Child Message");
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
package
import flash.display.MovieClip;
import flash.display.Loader;
import flash.net.URLRequest;
import flash.events.Event;
import flash.display.LoaderInfo;
import flash.display.Sprite;
import flash.text.*;
import flash.display.SimpleButton;
public class Parent extends MovieClip
private var loader:Loader;
public function Parent():void
loader = new Loader();
loader.contentLoaderInfo.addEventListener(Event.COMPLETE,
onLoadComplete);
loader.load(new URLRequest('Child.swf'));
private function onLoadComplete(e:Event):void
var loaderInfo:LoaderInfo = e.target as LoaderInfo;
addChild(e.target.content);
var swf:Object = loaderInfo.content;
swf.x = 75;
swf.y = 50;
public function ReceivingChildMsg(msg:String):void
// tp textfield object is created directly in flash
tp.text = msg;
