Event-Driven Actionscript

Question

I'm having problems with an actionscript project. I have to ask the user a question 5 times, the user has to answer and when the user clicks a button, the answer has to be validated.

Is there a way to make a for-loop wait for a click event?

What i was thinking of was something like this :

for(teller = 0; teller < 5; teller++){
   //show new question
   //user answers , and when finished the user clicks the button
   buttonNext.addEventListener(MouseEvent.CLICK,checkAnswer);                               
   //it has to wait until the user clicks the button , and then begin all over again
}

no, its a quiz, and the question has to show up when the user clicks the button, there are 5 questions — Thijs Cornelis

I'm confused you write "when the user clicks a button, the answer has to be validated" and now "question has to show up when the user clicks the button". Event driven mean you will write code for events, you listener "checkAnswer" is the place for do de validation. Why you want make a loop? — HMarioD

i've renewed the code fragment , hopefully that shows you what i mean — Thijs Cornelis

OK, I think I understand now, you don't need a loop, you need a global variable let say quizStatus to maintain the status the quiz, at the beginning you load it with 0 and each time you process the event in your handler "checkAnswer" you will check the status and act accordingly, when the user pass for the second question you increment the quizStatus variable. Do you understand what I'm trying do tell you? my english is very poor. — HMarioD

Yes, but do it in a different way (not using for loops):

var questionsAnswered = 0; //in class files put this higher up

nextQuestionButton.addEventListener(MouseEvent.CLICK, nextQuestion);
function nextQuestion(e:MouseEvent){
    trace(questionsAnswered);
    questionsAnswered++;
    // Logic here
}
