Playing Sounds

Ok, I need to know how to play sounds, this is what I have

(I have flash 8 pro)

I’ve gone to linkage, selected “export actionscript & first frame”

gave it the identifier “beep”

then used this code…

function start_interval()
{
    _global.interval = new Number(1);
    _global.beep_interval= new Number(setInterval(beep, interval*1000));
    trace("start_runs");
}

function stop_interval()
{
    beep.stop();
    trace("stop runs");
}
    


function beep()
{
    trace("runs billion times a second");
    beep.start(_global.interval*60, 999999);
}




//end

start_btn.onRelease = start_interval();
stop_btn.onRelease = stop_interval();

Thanks in advance
