Animator Is Not A Playable Error.

I am trying to make my player move with its animation i made. I made a script to allow it to move with WASD and Arrow keys and i made a separate script for the animations.

Moving Script:

 using System.Collections;
 using System.Collections.Generic;
 using UnityEngine;
 
 public class PlayerMovement : MonoBehaviour {
 
     public float moveSpeed;
 
     void Start ()
     {
         moveSpeed = 6f;
     }
     
     void Update ()
     {
         //Trigger Movement
         transform.Translate(moveSpeed * Input.GetAxis("Horizontal") * Time.deltaTime, 0f, moveSpeed * Input.GetAxis ("Vertical") * Time.deltaTime);
 
 
         }
     }
 }

Animation Script:

 using System.Collections;
 using System.Collections.Generic;
 using UnityEngine;
 
 public class Animations : MonoBehaviour {
 
     public Animator anim;
     public KeyCode MoveW;
     public KeyCode MoveA;
     public KeyCode MoveS;
     public KeyCode MoveD;
 
     void Start () {
         
     }
     
     void Update () {
         //Trigger Move Animation
         if (Input.GetKeyDown(MoveW))
         {
             anim.SetTrigger("MoveTrigger");
         }
     }
 }
