Class has be instantiated in document class but having issue..HELP

Question

Guys,
I am making my way with AS3 in little steps and have hit a
road block. This is what I have:
I have a document class called "Document Class"
I have a custom class called "Game"
I have instantiated an object of "Game" class and I am able
to trace a class method which return a simple "HELLO".
within my Game class, I have a variable(type Array) called
"questions" as instance variable.
I would like to add questions to "questions" array by using
"Mutator" method, or count the current elements with the questions
array and return the total number of questions. I am unable to add
or access elements to the questions array.
Any help would highly be appreciated, please.

Answer 1

First thing: you need to set the functions you're calling to
public, so that you have access to them outside of your class.
Second: you are initializing 'questions' to null. I made some
changes and it seems to work for me:
//////////////Game
Class///////////////////////////////////////////////
public function Game()
//this.questions = null;
this.correctAnswers = null;
this.userAnswers = null;
// SETQUESTION FUNCTION CAN ADD QUESTIONS TO THE QUESTION
ARRAY;
public function myArr():void
trace(questions.length);
public function AddQuestions(val:String)
this.questions.push(val);
trace(val);
}
