No collision detection problem

1

I quoted the lines that should have a collision detection but there is no collision for some reason :confused: can anyone help me. I traced it many times and that but no luck.

var allQuestions:Array = new Array();

function setupChoices(){
    
    var tempQuestion:question;
    tempQuestion = new question( 1 , "What are you doing here?" , 0xFF000 );
    
    var tempAnswer:answer;
    tempAnswer = new answer( "I'd like a café latté please." , trace , "EVERYTHING IS WORKING..." );
    tempQuestion.addAnswer( tempAnswer );
    
    tempAnswer = new answer( "Shut up." , doQuestion , 2 );
    tempQuestion.addAnswer( tempAnswer );
    
    // add finished question to list of all...
    allQuestions.push( tempQuestion );
    
    // question 2
    tempQuestion = new question( 2 , "What's it all about?" , 0xFF000 );
    tempAnswer = new answer( "It's about nothing." , trace , "Question two has been answered." );
    tempQuestion.addAnswer( tempAnswer );
    tempAnswer = new answer( "What did you ask me a second ago?" , doQuestion , 1 );
    tempQuestion.addAnswer( tempAnswer );

    allQuestions.push( tempQuestion );
    
    trace( allQuestions.length );
