Animation problems

Hey all

I'm having problems with getting two animation scripts to work. The first is with a door which I'm trying to get to open when the player walks into it, however it says it cannot find the animation I've made for it. Here is the code:

 var doorOpenSound : AudioClip;
 
 function Update () {
 
 }
 
 function OnControllerColliderHit (hit : ControllerColliderHit) {
 
     if(hit.gameObject.tag == "Door") {
 
     Debug.Log("Hello");
 
     var door : GameObject = hit.gameObject;
 
         OpenDoor(door);
 
     }
 
 }

 function OpenDoor(door: GameObject) {
 
     audio.PlayOneShot(doorOpenSound);
 
     door.animation.Play("opendoor");
 
 }

the second is to make a skeleton rise from the ground but the script says it doesn't know what hit is. Script is:

 function OnTriggerEnter (play : Animation){ 
     if (hit.gameObject.tag == "skeletonrise") { 
     Debug.Log("Hello"); 
         animation.Play("skeletonriseani"); 
     } 
 } 

Any help would be great. Thanks.
