Walking animation on a click to move script

Hi, i am having serious problems with this script i am trying to assemble from other scripts for a click to move character that walks while moving and stays still after:

using System;
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.UI;
using UnityEngine.Animations;

public class ClickToMove : MonoBehaviour
{
public Text countText;
public Text winText;
public Button WinButton;
public RawImage WinImage;

Animator anim;

private float speed = 20f;
private int count;
private Vector3 targetPosition;
private bool isMoving;

const int LEFT_MOUSE_BUTTON = 0;

// Use this for initialization
void Start()
{
    count = 0;
    SetCountText();
    winText.text = "";
    WinButton.gameObject.SetActive(false);
    WinImage.gameObject.SetActive(false);

    anim = GetComponent<Animator>();

    targetPosition = transform.position;
    isMoving = false;

}

// Update is called once per frame
void Update()
{
    if (Input.GetMouseButton(LEFT_MOUSE_BUTTON))
        SetTargetPosition();

    if (isMoving)
        MovePlayer();

}

void SetTargetPosition()
{
    Plane plane = new Plane(Vector3.up, transform.position);
    Ray ray = Camera.main.ScreenPointToRay(Input.mousePosition);
    float point = 0f;

    if (plane.Raycast(ray, out point))
        targetPosition = ray.GetPoint(point);

    isMoving = true;

    anim.Play("Correr");
}

void OnTriggerEnter(Collider other)
{
    if (other.gameObject.CompareTag("Pick Up"))
    {
        other.gameObject.SetActive(false);
        count = count + 1;
        SetCountText();
    }
}

void MovePlayer()
{
    transform.LookAt(targetPosition);
    transform.position = Vector3.MoveTowards(transform.position, targetPosition, speed * Time.deltaTime);

    if (transform.position == targetPosition)
        isMoving = false;

    anim.Play("Quieto");

    Debug.DrawLine(transform.position, targetPosition, Color.red);
}

void SetCountText()
{
    countText.text = " " + count.ToString();
    if (count >= 8)
    {
        winText.text = " ";
        WinButton.gameObject.SetActive(true);
        WinImage.gameObject.SetActive(true);
    }
}

}

Any ideas or fixes? Thanks
