How to modify the code to get started the timer on mentioned time?

Question

Hi,
I have the following code from a source. I would like to make a few changes as mentioned below:
First ....
1) The as3 code should get the time form "startMeeting_txt.text"
2) Compare it with current time from "currentTime_txt.text"
3) The Timer should be activated as soon as the "startMeeting_txt.text" = "currentTime_txt.text" and starts counting
4) When the "finishMeeting_txt.text" = "currentTime_txt.text" then
5) "message_txt.text" = "Meeting time is over"
How to modify the following code:
var count:Number = 60;
var myTimer:Timer = new Timer(1000,count);
myTimer.addEventListener(TimerEvent.TIMER, countdown);
myTimer.start();
function countdown(event:TimerEvent):void {
myText_txt.text = String((count)-myTimer.currentCount);
if(myText_txt.text == "0"){
      gotoAndStop(2)
Thanks.

Thanks. I am at work now and don't have Flash installed on my PC. I will try it at home. I just found this code on a website and wanted to know it more without any try. I must try it first then seek help. I am sorry.
I do respect your advise.
Regards.
