How to implement animation into a click to move script plzzzzzzz

So yh, I have this script which is suppose to move my thirdperson character(Ethan) when i tap on the screen, however when ever i try to implement animation it simply does work any ideas? :

 using UnityEngine;
 using System.Collections;
 
 public class TapToMove : MonoBehaviour {
     //flag to check if the user has tapped / clicked. 
     //Set to true on click. Reset to false on reaching destination
     private bool flag = false;
     //destination point
     private Vector3 endPoint;
     //alter this to change the speed of the movement of player / gameobject
     public float duration = 50.0f;
     //vertical position of the gameobject
     private float yAxis;
    static Animator anim;
 
     public Rigidbody rb;
     void Start()
     {
         //save the y axis value of gameobject
         yAxis = gameObject.transform.position.y;
      //   rb = GetComponent<Rigidbody>();
        anim = GetComponent<Animator>();
     }
 
     // Update is called once per frame
     void Update()
     {
 
         //check if the screen is touched / clicked   
         if ((Input.touchCount > 0 && Input.GetTouch(0).phase == TouchPhase.Began) || (Input.GetMouseButtonDown(0)))
         {
             //declare a variable of RaycastHit struct
             RaycastHit hit;
             //Create a Ray on the tapped / clicked position
             Ray ray;
             //for unity editor
 #if UNITY_EDITOR
             ray = Camera.main.ScreenPointToRay(Input.mousePosition);
             //for touch device
 #elif (UNITY_ANDROID || UNITY_IPHONE || UNITY_WP8)
    ray = Camera.main.ScreenPointToRay(Input.GetTouch(0).position);
 #endif
 
             //Check if the ray hits any collider
             if (Physics.Raycast(ray, out hit))
             {
                 //set a flag to indicate to move the gameobject
                 flag = true;
                 //save the click / tap position
                 endPoint = hit.point;
                 //as we do not want to change the y axis value based on touch position, reset it to original y axis value
                 endPoint.y = yAxis;
                 Debug.Log(endPoint);
             }
 
         }
         //check if the flag for movement is true and the current gameobject position is not same as the clicked / tapped position
         if (flag && !Mathf.Approximately(gameObject.transform.position.magnitude, endPoint.magnitude))
         { //&& !(V3Equal(transform.position, endPoint))){
           //move the gameobject to the desired position
 
             anim.SetFloat("Forward", 1.0);
             gameObject.transform.position = Vector3.MoveTowards(gameObject.transform.position, endPoint, 1 / (duration * (Vector3.Distance(gameObject.transform.position, endPoint))));
         }
         //set the movement indicator flag to false if the endPoint and current gameobject position are equal
         else if (flag && Mathf.Approximately(gameObject.transform.position.magnitude, endPoint.magnitude))
         {
             flag = false;
             Debug.Log("I am here");
         }
       }
 }
