24 hours looping countdown clock

Hi i am trying to create a 24 hour countdown clock that will loop and play backwards counting it self back down to 00:00:00:00, being new to flash As3 i am struggling to create this animation

the AS3 code i have put into my actions is as follows:

var timer:Timer = new Timer(1000);
var currentSeconds:int = 86400;
var milliseconds:int = 86400000;
var result:String = “”;

timer.addEventListener(TimerEvent.TIMER, countDown);

function countDown(e:TimerEvent):void {

currentSeconds -= 1;
milliseconds -= 1000;

var minutes:int = (currentSeconds / 60 >= 1)?currentSeconds / 60:0;
var hours:int = minutes*60;
var seconds:int =
currentSeconds < 59?currentSeconds:currentSeconds - (int(currentSeconds / 60)*60);

result = ((hours >= 10)?hours:“0”+hours)+":"+((minutes >= 10)?minutes:“0”+minutes) +":" + ((seconds >= 10)?seconds:“0”+seconds)+":"+milliseconds/100+"";

}

When i press to test the movie the numbers are still 00:00:00:00

if any one could shed some light on what i am doing wrong it would be very helpfull !

below i have attached a link to an image to give a better idea of where i am at with this animation:

thanks in advance
