[F8] Countdown timer problem= NaN:NaN etc

[hiab-x]

Hi, I recently followed a video tutorial to the letter, to create a countdown timer in Flash8. All seemed to be going well until I completed the actionscript & hit 'preview' Instead of getting 00:00:00:00 (Days+Hours+Minutes+Seconds)
I got a rather taunting (unexpected) NaN:NaN:NaN:NaN

I'm an utter novice with script so I was left pretty stumped. I'll paste the exact code below the dotted line & hopefully some bright spark visiting here might be able to tell me how to fix the problem. I hope so.
.................................................. .................................................. .....

this.onEnterFrame = function() {
var today:Date = new Date();
var currentYear = today.getFullYear();
var targetdate:Date = new Date(currentYear, 04, 20);
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;
}

For what its worth, there are no apparent problems as far as debugging is concerned. No errors flash up. The full tutorial can be found at this address...

If you can help, please give me a holler. Thanks

well here is the problem NaN means Not a Number........it pops up when you do some funky math calculation that flash doesn't understand. find a new timer script there are a bunch out there that are wrote better than the above script.

there are a couple of mistakes. First actionscript is case sensitive:
targetdate and targetDate are 2 separate vars.

also you have this: var timeLeft = targetTime-currentTime;
but currentTime is not defined anywhere.

Thanks for the 'heads up', I'll correct the targetDate typo & re-check the video tutorial to see if I can identify the missing script. In the meanwhile, thanks for helping me.

gparis, thanks very much for pointing out the errors in my actionscript. They were subtle & would've taken me significantly longer to spot without your well trained eye. The timer works a treat now. :-)
