Actionscript 3.0: Accessing Dynamic text from AS3 class to Game - string

Question

I have here a bubble popping game where bubbles fall from top of the game to the bottom and the player tries to pop as many bubbles as possible in 30 seconds. It is a 3 frame game, 1st frame is the start button, 2nd frame is the game, 3rd frame is the score and play again.
1st frame: Buttons to go to the second frame
2nd Frame: timer to count 30 seconds of play time
3rd frame: buttons to play again.
ScoreValue is a dynamic textbox in the last frame of the game. It records the points based on size the size scale of the bubble, and should be change based on the amount of bubbles the player has popped.
scoreValue.text = score.toString();
Error 1120: Access of unidentified property scoreValue
Anyways here the full package of the code.
package {
import flash.display.MovieClip;
import flash.events.Event;
import flash.media.Sound;
import flash.geom.ColorTransform;
public class Ball extends MovieClip{
static public var burstCounter: uint;
private var vx: Number;
private var vy: Number;
private var gravity: Number;
private var stageWidth;
private var stageHeight;
private var bubble:Ball = new Ball();
private var score: uint=0;
public function Ball() {
bubble.addEventListener(Event.ADDED_TO_STAGE, initialize)
bubble.addEventListener(MouseEvent.CLICK, burst)
bubble.addEventListener(Event.ENTER_FRAME, dropping)
}
public function initialize (e:Event):void
{
bubble.x = Math.random() * stageWidth;
bubble.y = 0;
stageWidth = stage.stageWidth;
stageHeight = stage.stageHeight;
bubble.vx = Math.random() * 2 - 1;
bubble.vy = Math.random() * 2 + 1;
gravity = 0.1;
var sizeScale = Math.random() * 1.2 + .6;
bubble.scaleX = bubble.scaleY = sizeScale;
score = (10 / sizeScale);
scoreValue.text = score.toString();
var colorTran = new ColorTransform();
colorTran.color = Math.random() * 0xFFFFFF;
transform.colorTransform = colorTran;
addChild(bubble);
}
function dropping(e: Event) :void
{
x += vx;
y += vy;
vy += gravity;
if((x<0) || (x>stageWidth) || (y<0) || (y>stageHeight))
{
if(parent != null)
{
parent.removeChild(this);
}
removeEventListener(Event.ENTER_FRAME, dropping)
}
}
function burst (e:Event):void
{
var ballonPopping: Sound = new BalloonPopping();
bubble.removeEventListener(Event.ADDED_TO_STAGE, initialize);
bubble.removeEventListener(Event.ENTER_FRAME, dropping);
removeChild(bubble);
ballonPopping.play();
burstCounter += score;
}
}
}
Im getting this as output in my program, does any one know why?
Fonts should be embedded for any text that may be edited at runtime, other than text with the "Use Device Fonts" setting. Use the Text > Font Embedding command to embed fonts.
Thanks for your time.

Answer 1

you need to import the MouseEvent class to fix the 'Access undefined property of MouseEvent'
add this to your import statements:
import flash.events.MouseEvent;

Answer 2

Firstly, in a class, functions should be defined as public or private. Second, your burst function is expecting an Event while you are assigning a MouseEvent to it. Its an easy mistake that I use to often do.
Change it to:
private function burst (e:MouseEvent):void
The font thing in the output panel means you have a dynamic text field somewhere. Simply go to your FLA, open up that textfield and on the properties panel, hit the embed button and choose the Basic Latin checkbox...or numerals if its just numbers
edit: Also change your import to
import flash.events.*;
or add
import flash.events.MouseEvent;
