Playing Sounds using ActionScript

Hi,

I found this tutorial (http://www.kirupa.com/developer/actionscript/sound.htm) and is great but I want to play an intro 1 time and after the intro music is over play my loop. How can I achive this?

on (release) {
   kirupaSound = new Sound(this);
   kirupaSound.attachSound("coolsound");
   kirupaSound.start(0, 99);
}

Thank you on advance.:thumb:
