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.selected) {

                              thisMany ++;

                    }

          }

          if(thisMany == 4) {

                    //do something

          } else {

                    // do something else

          }

}
