[SOLVED]Need OnTriggerEnter Help

Hi guys,

I'm trying to trigger animations with the function OnTriggerEnter. I want the player to hit the button and trigger the door animation. I have included a little diagram of what I am wanting to do.

I'm using unity 5.2.

I've already tried the code below. I put this code on the door parent, with the animation applied to the door parent. But when the player hits the button it doesn't trigger the animation.

Code:

 using UnityEngine;
 using System.Collections;
  
 public class Door1 : MonoBehaviour {
  
     Animator animator;
     bool doorOpen;
  
     void Start()
     {
         doorOpen = false;
         animator = GetComponent<Animator>();
     }
  
     void OnTriggerEnter(Collider col)
     {
         if (col.gameObject.tag == "Player")
         {
             doorOpen = true;
             DoorControl ("Open");
         }
     }
  
     void DoorControl(string direction)
     {
         animator.SetTrigger (direction);
     }
 }

I've also tried other code with it attached to the button and the collider set to "is trigger", but that didn't work either.

I would truly appreciate any help.

Thanks in advance.
