[Flash 8] Dynamic Text Field Doesn't Return Value Calculated in ActionScript

Hello,

I am having trouble getting my dynamic text field to populate based on a countdown ActionScript. My dynamic text field’s attribute name is time_txt and is set to Dynamic Text in the Properties panel. Here is my code:

 this.onEnterframe = function() {
    
    //Gets current date, year, and time
    var today:Date = new Date ();
    var currentYear = today.getFullYear();
    var currentTime = today.getTime();
    
    //Denotes target date that we are counting down to
    var targetDate:Date = new Date (2008,06,12);
    var targetTime = targetDate.getTime();
    
    //Calculates the actual time left between the current date and target date
    var timeLeft = targetTime - currentTime;
    
    //Converst milliseconds into seconds, minutes, hours, and days
    var sec = Math.floor(timeleft/1000);
    var min = Math.floor(sec/60);
    var hrs = Math.floor(min/60);
    var days = Math.floor(hrs/24);
    
    //Stores remainders of seconds so 130 seconds doesn't look like 2 minutes, 130 seconds, but rather 2 minutes 10 seconds
    //Converts sec to a string
    //Accounts for sec values under 10 so that 5 reads 05 
    sec = string(sec % 60);
    if (sec.length < 2) {
        sec = "0" + sec;
    }
    
    //Stores remainders of minutes so 130 seconds doesn't look like 2 hours, 130 minutes, but rather 2 hours 10 minutes
    //Converts min to a string
    //Accounts for min values under 10 so that 5 reads 05 
    min = string(min % 60);
    if (min.length < 2) {
        min = "0" + min;
    }
    
    //Stores remainders of hours so 25 hours doesn't look like 1 day, 25 hours, but rather 1 day 1 hour
    //Converts hrs to a string
    //Accounts for hrs values under 10 so that 5 reads 05 
    hrs = string(hrs % 24);
    if (hrs.length < 2) {
        hrs = "0" + hrs;
    }
    
    //Converts days into a string
    days = string(days);
    
    //String together days, hours, minutes, seconds
    var counter:String = days + ":" + hrs + ":" + min + ":" + sec;
    
    //Update dynamic text field
    time_txt.text = counter;
    
}

Any ideas?

Thanks!
