Help with Animator has not been initialized error

Every time I try to run the game I get the error: Animator has not been initialized. UnityEngine.Animator:SetFloat(String, Single)

Here's the portion it's calling the error on:

anim.SetFloat("Speed", speed); anim.SetFloat("Move", isMoving);

And here's the whole script:

 public class PlayerMovement : MonoBehaviour
     {
         public float speed = 1f;
         public Vector3 touchPoint;
         public float isMoving = 1f;
         
     public Animator anim; 
     void Update()
     {
         anim.SetFloat("Speed", speed);
         anim.SetFloat("Move", isMoving);
         
         // Lerps to the last position touched, going to have to modify this
         // to only work when tapped not hold cause shooting will be hold.
         
         if (Input.touchCount > 0 )
         {
             // Shoots a ray where you touched the screen
             RaycastHit hit;
             // There was an error before. The tag must be main camera.
             Ray ray = Camera.main.ScreenPointToRay(Input.touches[0].position);
             
             if (Physics.Raycast(ray, out hit, Mathf.Infinity))
             {
                 // converts the touch point to unitys 3d worldspace Vector3
                 touchPoint = hit.point;                                                                         
             }
         }
         MoveToPos(touchPoint);
         //isMoving = (Mathf.Abs(transform.position.z - touchPoint.z)* 10);
     }
     void MoveToPos(Vector3 touchPoint)
     {          
         gameObject.transform.position = Vector3.Lerp(gameObject.transform.position, new Vector3(touchPoint.x, 10, touchPoint.z), speed * Time.deltaTime);    // LAWL this had to be z even tho im using y for droid , wasted alot of time on that.  
         //gameObject.transform.LookAt(touchpoint);
     }
