Flash question (if / else)

Question

Hey guys,
I just found a video tutorial online that was kinda helpful for my homepage.
I want to change one thing though, (and tried for the last 2 hours) but I don't really (or at all) get it to work how I want it.
http://www.republicofcode.com/tutorials/flash/video/countdown.php
This is the tutorial and it creates a countdown timer in flash.
Following the Actionscript, what I want to accomplish is that the timer actually stops after the event has happened and displays some kind of a text.
I tried playing around with an if statement (the last line), something like
if (counter > 0) {
     time_txt.text = counter;
} else {
     time_txt.text = "Random Text";
but that did not work for me, and I honestly don't know why.
Attached the entire Actionscript if somebody wants to help me.
Thanks in advance.

this.onEnterFrame = function()    {
    var today:Date = new Date();
    var currentYear = today.getFullYear();
    var currentTime = today.getTime();
    var targetDate:Date = new Date(2009,5,27);
    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;
