Help using multiple if else statements & manual dynamic xml data input to trigger a goto and play.

Question

Below is code that has a timer countdown that reads off of the computer. Below in bold is code to read "if it reaches the date, go to and play frame (2).
timer.removeEventListener(TimerEvent.TIMER, updateTime);
  timer.stop();
  gotoAndPlay(2);
Below is code that is manual input-   I had set up a dynamic txt field in flash named it : raffle_tix_remain When loaded on to the host I can manulally update the xml code and the change will take effect.
raffle_tix_remain.text = root.loaderInfo.parameters.raffle_tix_remain;
My question:  Since the raffle_tix_remain is a manual input from a user to xml  Is there a way to tell flash once it refreshes and "raffle_ tix_ remain"  goes to (0) zero gotoAndPlay(2); and let it play like a "sold out" sign
i guess that would be a  if else statement. 
Code Below-----------------
stop();
var year:Number = 2011;
var month:Number = 12;
var day:Number = 30;
var finalDate:Date = new Date(year,month-1,day);
var timer:Timer = new Timer(100);
timer.addEventListener(TimerEvent.TIMER, updateTime);
timer.start();
function updateTime(e:TimerEvent):void{
          var now:Date = new Date();
          var remainTime:Number = finalDate.getTime() - now.getTime();
          if (remainTime >0) {
                    var secs:Number = Math.floor(remainTime/1000);
                    var mins:Number = Math.floor(secs/60);
                    var hours:Number = Math.floor(mins/60);
                    var days:Number = Math.floor(hours/24);
                    var secsText:String = (secs%60).toString();
                    var minsText:String = (mins%60).toString();
                    var hoursText:String = (hours%24).toString();
                    var daysText:String = days.toString();
                    if (secsText.length < 2) {secsText = "0" + secsText;}
                    if (minsText.length < 2) {minsText = "0" + minsText;}
                    if (hoursText.length < 2) {hoursText = "0" + hoursText;}
                    if (daysText.length < 2) {daysText = "0" + daysText;}
                    day_txt.text = daysText;
                    hour_txt.text = hoursText;
                    min_txt.text = minsText;
                    sec_txt.text = secsText;
          else {
                    timer.removeEventListener(TimerEvent.TIMER, updateTime);
                    timer.stop();
                    gotoAndPlay(2);
