How do I play death animation in the animator controller properly

I am having a problem playing my die animation on my animator controller . I have the animation set as a trigger . I even coded a line code as trigger and I still couldn’t get the animation to play. Now I have it set as a tag. I still cant get it to work . I also have a pic.

I got one error NullReferenceException: Object reference not set to an instance of an object Opsive.ThirdPersonController.Health.DieLocal (Vector3 position, Vector3 force) (at Assets/Third Person Controller/Scripts/Health.cs:357)
This all I got in the start function.
void Start ()
{
anim = GetComponent ();
}

if (m_DeactivateOnDeath) {
Scheduler.Schedule(m_DeactivateOnDeathDelay, Deactivate);
anim = GameObject.FindGameObjectWithTag(“Death”).GetComponent();
GetComponent().Play();
}
}

I had change the parameter and code : I got this error : Controller ‘bear’: Transition ‘’ in state ‘AnyState’ uses parameter ‘Death’ which does not exist in controller.
Here is what I got now.
UnityEditor.DockArea:OnGUI()

  if (m_DeactivateOnDeath) {
                Scheduler.Schedule(m_DeactivateOnDeathDelay, Deactivate);
                    GetComponent<AudioSource>().Play();
                    anim.SetTrigger("Dead");
            }
        }
