Audio not playing [Fixed]

 #pragma strict
     
 
 var isQuitButton = false;
 var isInfoButton = false;
 
 var sound1 : AudioClip;
     
     function OnMouseEnter () {
         renderer.material.color = Color.red;
     }
         function OnMouseExit () {
         renderer.material.color = Color.white;
     }
         function OnMouseUp(){
             if(isQuitButton){
             Application.Quit();
             audio.PlayOneShot(sound1);
             }
             else if(isInfoButton){
             Application.LoadLevel(2);
             audio.PlayOneShot(sound1);
             }
             else{
             Application.LoadLevel(1);
             audio.PlayOneShot(sound1);
             }
         }

When i click on the text it says; "MissingComponentException: There is no 'AudioSource' attached to the "Play_text" game object, but a script is trying to access it. You probably need to add a AudioSource to the game object "Play_text". Or your script needs to check if the component is attached before using it." even though i have a .WAV file attached to it.
