How do you run an animation for a character by pressing a Key with C#?

So far I have made the animations and created triggers to accommodate the animations for hitting and running. The animation I am trying to run is called PlayerHit-1 And the key I am trying to make call the trigger is w

This is my code so far

using UnityEngine; using System.Collections;

public class Player : MonoBehaviour { private Animator animator;

 // Use this for initialization
 void Start () 
 {
     animator = GetComponent<Animator>();
 }
 
 // Update is called once per frame
 void Update () {
     if(Input.getKeyDown("w"))
     {
         animator.SetTrigger("PlayerHit-1");
     }
 }

}

Please help, I am a noob..
