Error BCE0023 when using script for main menu

Hi, I’m trying to apply sounds when I either enter a 3d text with my mouse, or exit it. However, I get this error, /Assets/Scripts/TextControl.js(13,11): BCE0023: No appropriate version of ‘UnityEngine.AudioSource.Play’ for the argument list ‘(String)’ was found. Here’s my script:

var isQuitButton = false;
var LoadCamTime : float = 3;
var CamObj : GameObject;
var EnterS : AudioClip;
var Exit1 : AudioClip;



function OnMouseEnter ()
{ 

renderer.material.color = Color.red;
audio.Play("EnterS");
}


function OnMouseExit ()
{ 

renderer.material.color = Color.white;
audio.Play("Exit1");
}


function OnMouseUp ()
{






if(isQuitButton) 
{
Application.Quit();
}

else

CamObj.animation.Play("LoadCamLev1");
yield WaitForSeconds(LoadCamTime);
Application.LoadLevel(1);

}

There is no function AudioSource.Play() that takes a string as an argument. See AudioSource.clip for the correct way to play an audio clip.
