Could anyone help me with this Countdown code, I have followed a tutorial exactly and it still comes out wrong.

Basicaly I have created a dynamic textbox on an unlabled layer I have embded the fonts and labled the text box "time_txt" then added a new layer and labled it "actions" then on the first slot I've added the code as follows:

this.onEnterFrame = function() {

var todayate = new Date();
var currentYear = today.getFullYear();
var currentTime = today.getTime();

var targetDateate = new Date(currentYear,9,24);
var targetTime = targetDate.getTime();

var timeLeft = targetTime - currentTime;

var sec = Math.floor(timeLeft/1000);
var min = Math.floor(sec/60);
var hrs = Math.floor(min/60);
var days = Math.floor(hrs/24);
sec = string(sec % 60);
if (sec.length < 2) {
sec = "0" + sec;
}
min = string(min % 60);
if (min.length < 2) {
min = "0" + min;
}
hrs = string(hrs % 24);
if (hrs.length < 2) {
hrs = "0" + hrs;
}
days = string(days);

var counter:String = days + ":" + hrs + ":" + min + ":" + sec;
time_txt.text = counter;
}

I want it to count down to 24/09/2007 (the date season 2 of Heroes is out)

Hope someone can help.
