Multiple sounds on single frame problem

programming flash

I have two buttons on a single frame that each play seperate sounds when clicked though actionscript is throwing up this error and I have no idea how to fix it.

Can anyone help?

stop();

var snd:Sound2= new Sound2();

Clock_btn.addEventListener (MouseEvent.CLICK, soundbutton_Handler);

function soundbutton_Handler (e:MouseEvent):void 
{
snd.play();
}

stop();

var snd:Mysound3= new Mysound3();

Stamina_btn.addEventListener (MouseEvent.CLICK, soundbutton_Handler);

function soundbutton_Handler (e:MouseEvent):void

snd.play();
}
