Multiple choice checkboxes

Question

Hi
I was wondering if anyone help me.
I hav a mutliple choice question where you have to select 4 answers.
How can I disable the submit button until 4 checkboxes have been selected?
Here is my code so far:
submitButton.addEventListener(MouseEvent.CLICK, testHandler);
function testHandler(event:MouseEvent):void
     var minAnswers:int = 4;
     var maxAnswers:int = 4;
     var selectedAnswers = 0;
     var totalCheckboxes:int = 6;
     for (var checkboxNumber:int = 1; checkboxNumber <= totalCheckboxes; checkboxNumber++)
          if (this['answer_' + checkboxNumber].selected == true)
               // increment selected answers
               selectedAnswers++;
     if ( selectedAnswers >= minAnswers && selectedAnswers <= maxAnswers)
                    if((answer_1.selected) && (answer_2.selected) && (answer_4.selected) && (answer_6.selected)){
                              testtext.text = "Thats correct!.";
     else
                    testtext.text = "Thats incorrect";
Can anyone help me?
Many thanks

I think this will do what you want, if I'm reading you right:
// make an array of the question checkboxes...
var qList:Array = new Array(answer_1,answer_2,answer_3,answer_4);
submitButton.addEventListener(MouseEvent.CLICK,testHandler);
// then in the button function count the number of checkboxes that have been selected and do one thing or another based on the count...
function testHandler(event:MouseEvent):void {
          var thisMany:int = 0;
          for (var i:String in qList) {
                    if (qList[i].selected) {
                              thisMany ++;
          if(thisMany == 4) {
                    //do something
          } else {
                    // do something else
