Java Script: Clock script help.

Hello, I was wondering if anyone could help me on this! I have this clock script and i want it to play a sound and play animations on multiple objects when it hits zero. Help?

#pragma strict

var timer : float = 10.0;

function Update () 
{
	timer -= Time.deltaTime;
	
	if(timer <= 0)
	{
		timer = 0;
		
	}
}

function OnGUI ()
{
	GUI.Box(new Rect(10,10,50, 20), "" + timer.ToString("0"));
}

if(Timer == 0)
{
animation.play(“animation”);
}

I can’t remember how to do the audio script part.
