About selected in radio button

1

Hai…I’ve a problem about quiz. So, if I was answered the first question with click one of 2 radio button and then clicked next button to see next questions…I found radio button was selected and I want that’s radio button not selected…How to do that? I use rb1.selected = false buat that’s useless …


import fl.controls.RadioButton;
import fl.controls.RadioButtonGroup;

stop();

var currIndex:Array;
var playerScore = 0;
var noSoal:int=0;
var k:int=1;

//var flag:int;

var rbGroup:RadioButtonGroup = new RadioButtonGroup("pilihanGanda");	
var rb1:RadioButton = new RadioButton();
var rb2:RadioButton = new RadioButton();
rb1.x = 52;
rb1.y = 96;
rb2.x = 52;
rb2.y = 123.7;
rb1.group = rbGroup;
rb2.group = rbGroup;


function indexSoal():Array
{
    var i:uint=0;
    var arr:Array = [];
    while (i<myXML.quiz.length())
    {
        arr.push(i);
        i+=1;
    }
    return arr;
}


//trace(rb1);
addChild(rb1);
addChild(rb2);		
	
	
//radio();
function radio()
{
	rb1.selected = false;
	rb2.selected = false;
	addChild(rb1);
	addChild(rb2);		
}
	

showData();
function showData()
{
	txtSoal.text = myXML.quiz[currIndex[noSoal]].soal;
    rb1.label = myXML.quiz[currIndex[noSoal]].pilihanGanda.pilihan[0];
    rb2.label = myXML.quiz[currIndex[noSoal]].pilihanGanda.pilihan[1];
}

//listener
btnNext.addEventListener(MouseEvent.CLICK, btnNextClicked);

function btnNextClicked(e:MouseEvent):void
{
	var answer:String = checkAnswer();
	if(answer != "none")
	{
		//hitung score
		if(answer == String(myXML.quiz[noSoal].jawaban))
		{
			playerScore += 1;
		}
		removeChild(rb1);
		removeChild(rb2);					
		
		noSoal++;
		k++;
		if(k <=5)
		{
			radio();
			showData();
			updateButton();
		}
		else
		{
			gotoAndStop("score");
		}
	}
}


//update button
function updateButton()
{
	if(k <= 5)
	{
		btnNext.label = "Finish";
	}
	else
	{
		btnNext.label = "Next";	
	}
}

//process check answer
function checkAnswer():String
{
	if(rb1.selected)
	{
		return String(rb1.label);
	}
	else if(rb2.selected)
	{
		return String(rb2.label);
	}
	return "none";
}
