Help with a countdown clock

1

Hi, I’m trying to create a countdown clock but I’m getting an error when I export my FLA. I used an online tutorial that I found here:
http://www.oman3d.com/tutorials/flash/video/countdown.php

I appreciate any help anyone :q: can provide…Here’s my code:

this.onEnterFrame = function() {
    
    var today:Date = new Date();
    var currentYear = today.getFullYear();
    var currentTime = today.getTime;
    
    var targetDate:Date = new Date(CurrentYear,3,13)
    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;
    
}
