Best way to add a score to a score box and total it up.

Question

I am creating a game for children to make good food choices
for breakfast, lunch, dinner, and snacks. I need to have the food
choice add a value to a score box when clicked onto the plate and
subtract the same amount when clicked off. So far, all I have been
able to do is get the score to appear in the upper left hand
corner. When I can get the pancakes working properly, I will be
adding other foods which will do the same thing with different
numbers. The total score cannot go over 100. I am attaching the .as
code, but it is separate from the .fla and I'm not sure if I can
upload the .fla here.

Answer 1

That worked! Now, I have another problem I can't seem to
figure out--when I add another food, berries, all it is doing is
moving the pancakes and not itself! Here is the revised coding:
package
//import any class being used by this package
import flash.display.MovieClip;
import flash.text.TextField;
import flash.text.TextFormat;
import flash.events.MouseEvent;
public class MealGame extends MovieClip
//altered version
var offPlate:Boolean; //variable for food off the plate
var gameScore:int = 0;
public function MealGame()
//Create a score field for the pancakes.
var gameScoreField:TextField = new TextField();
// set the position values
gameScoreField.x = 445;
gameScoreField.y = 530;
//Show the score field
addChild(gameScoreField);
var tf:TextFormat = new TextFormat();
var scoreBox:Object = getChildAt(numChildren-1);
//scoreBox.x = 445;
//scoreBox.y = 530;
//Create a new instance of the meal class.
var pancakes1:Pancakes = new Pancakes();
var berries1:Berries = new Berries();
//Display the food on this stage.
this.addChild(pancakes1);
this.addChild(berries1);
//Position the food item.
pancakes1.x = 11;
pancakes1.y = 42;
berries1.x = 211;
berries1.y = 396;
offPlate = true;
//make the food item a button
pancakes1.buttonMode = true;
pancakes1.addEventListener(MouseEvent.CLICK, onClick);
berries1.buttonMode = true;
berries1.addEventListener(MouseEvent.CLICK, onClick);
//toggle the food item to put on plate or off the plate
//toggle adding to the score or removing from the score
function onClick(event:MouseEvent):void
if(offPlate)
pancakes1.x = 119;
pancakes1.y = 380;
berries1.x = 515;
berries1.y = 55;
//add to score
gameScore = gameScore + 50;
gameScoreField.text = " " + String(gameScore);
tf.font = "Arial";
tf.bold = true;
tf.color = 0x000000;
tf.size = 32;
//Take this text formatting object; apply it to the
textfield
gameScoreField.setTextFormat(tf);
//toggle the offPlate value
offPlate = !offPlate;
else
pancakes1.x = 11;
pancakes1.y = 42;
//berries1.x = 211;
//berries1.y = 396;
//remove from score
gameScore = gameScore - 50;
gameScoreField.text = " " + String(gameScore);
tf.font = "Arial";
tf.bold = true;
tf.color = 0x000000;
tf.size = 32;
//tf.x = 426;
//Take this text formatting object; apply it to the
textfield
gameScoreField.setTextFormat(tf);
offPlate = !offPlate;
}
