Activating an animation upon triggering the collider?

Hi there!

So I'm trying to trigger an animation when I'm inside the collider which will move the chair back upon a mouse click. I'm just quite confused on how to integrate it inside the OnTriggerEnter? Clicking on the mouse still triggers the animation despite being outside the collider. I was wondering if there's a simpler way of integrating the trigger with the collider?

Thanks!

 public var chairAnimator: Animator;
 public var isChairMoved : boolean = false ; 
 public var isChairActive : GameObject ;
 
 function Start () {
 
 }
 
 function OnTriggerEnter (other: Collider){
     isChairActive.SetActive(true);
 }
 
 function OnTriggerExit (other: Collider){
     isChairActive.SetActive(false);
 }
 
 function Update () {
     if (Input.GetMouseButtonDown(0)){
         if (isChairMoved == false){
             Debug.Log("Mouse Clicked");
             chairAnimator.Play("Chair_Moved_Backwards");
         }else{
             chairAnimator.Play("Chair_Moved_Forwards");
         }
         isChairMoved = !isChairMoved;
     }
 }
