Door will not open with the press of a button

This has probably been answered on here a thousand times but I cant find anything that helps my situation. I am trying to make a door that opens when you press E. I have followed the tutorial perfectly and still nothing will work. I have my 4 animations (DoorOpen, DoorOpened, DoorClose, and DoorClosed) I have the box collider around the door as a trigger. Any ideas?

  //The Base Door script will allow functionality for any kind of door
  //When the PLAYER enters a Trigger Volume, and presses the INTERACT key,
  //the door will change states (open>close, close>open)
  
  
  Animator anim;
  public GameObject hinge;
  
  // Use this for initialization
  void Start () {
  
      anim = hinge.GetComponent<Animator>();
  
  }
  
  // Update is called once per frame
  void Update () {
  
      if(anim.GetCurrentAnimatorStateInfo(0).IsName("DoorOpen") || anim.GetCurrentAnimatorStateInfo(0).IsName("DoorClose")) 
      {
          anim.SetBool ("DoorInteract", false);
      }
  }
  
  void onTriggerStay(Collider other)
  {
      if (other.tag == "Player")
      {
          if (Input.GetKey(KeyCode.E))
          {
              anim.SetBool ("DoorInteract", true);
          }
      }
  }
