Switch/case help

I’m making a countdown timer, and I want different events to be triggered at different stages of the time. I’m using getTimer to calculate how long is left to an arbitrary finishtime.

The problem I am having is I am trying to use the switch/case command to trigger the events. All that happens, even when elapsedTime goes beyond the required time, is that it goes the default clause. Any idea how I can use ranges of numbers within the case clauses?

[font=Courier New]_root.onEnterFrame = function() {
currentTime = getTimer();
elapsedTime = Math.round((finishTime - currentTime)/1000);
switch (elapsedTime) {
case elapsedTime<=0 :
trace(“finished”);
case elapsedTime<=10 :
trace(“10 seconds to go”)
case elapsedTime<=60 :
trace(“less than one minute”);
default:
trace(“long way to go yet”)
}
countdownTime.text = Math.floor(elapsedTime/60) + “:” + elapsedTime%60;
}[/font]
