cant stop my animation

how do i stop my animation from looping over and over again?

 ccc.animation.wrapMode = WrapMode.Once;
 ccc.animation.Play("Intro");

that works, but it loops the animation agian and again, i also tried

      ccc.animation.Play("Intro");
      if(!ccc.animate.IsPlaying("Intro"))
      {
      ccc.animation.Stop
      }
 and
 ccc.animation.Play("Intro");
 yield WaitForSeconds (animation.clip.length);

ccc is the variable i assigned to the camera,

 var ccc : GameObject;
 ccc = GameObject.Find("Camera")
