This is the class that works the dragonwork.fla which only uses this class and nothing else.
package 
{
//**************************** BRINGING IN THE NECESSARY HELP FILES **************************
import flash.display.*; // for placing items on the stage
import flash.text.*;
import flash.events.*;  // for watching out for events that happen during play
import flash.net.URLRequest; // for setting up an actual outside connection
import flash.events.IOErrorEvent; // for checking to see if errors occur
import rebarr.*;
public class DragonWork extends MovieClip
{
  private var thisdragon:Dragon = new Dragon("thedragon.xml","thisdragon");
  private var theage:Number;
  private var thetext:TextField = new TextField();
  private var textlook:TextFormat = new TextFormat();
  public function DragonWork()
  {
   addChild(thisdragon);thisdragon.x = 200; thisdragon.y = 250;
   textlook.font = "Helvetica"; textlook.size = 24; textlook.bold = true;
   addChild(thetext); thetext.x = 100; thetext.y = 100; thetext.width = 250; thetext.height = 30;
   theage = thisdragon.myAge; trace("age of the dragon is ", theage);
   thetext.text = thisdragon.growth; thetext.setTextFormat(textlook);
  
  }

}

}


This is inside the rebarr directory.

This is the xml File that gets used

<?xml version="1.0" encoding="utf-8"?>
<thedragon>
<dragon>
  <myname>Rashana</myname>
  <myage>250</myage>
  <birthday>614578930224</birthday>
  <myrider>rbert</myrider>
  <myfile>images/dragons/green6.gif</myfile>
  <mygender>female</mygender>
  <mycolor>green</mycolor>
</dragon>
</thedragon>

What I am not understanding is why the growth variable will not print anything out.  It is probably something simple that I cannot see because of the forest but I do not know for sure.  Can someone give me an idea as to what is wrong here.

well what i think is happening here is that for some reason the dragon class init function is not called before you set the text and thus the growth string is null./ what you can do is set the string to lets say growth="test" and see if it prints out. also i dont think it is a good idea to build such a dependancy on a public variaple you should maybe dispatch an event when the growth is changed and the handler function then can print the growth or what ever you see fit

To be honest, I didn't want to make the variable public.  I tried setting up a method inside the class so that it could be gotten from the class by a call from another class but that did not seem to work either.  I am not sure what you mena by your suggestion, could you elaborate on it a bit. Please.

well you do like this:

inside the dragon class where you set the growth after that you write:

dispatchEvent(new MyEvent("growth",grotwh));

then you make a new class called MyEvent like this:

import flash.events.Event;

public class MyEvent extends Event{

public var VALUE::String;

public function MyEvent(name:String,value:int){

  super(s);

  VALUE = value;

}

}

and now in your main you just set an eventListener to the dragon class instance like this

var dragoninstance:Dragon = new Dragon();

dragoninstance.addEventListener("growth",handleGrowth);

function handleGrowth(e:MyEvent){

mytext.text = e.VALUE;

}
