I can't get the character to turn around

The character doesn’t turn around. *pressing the left button

Here is my script:
using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class Player : MonoBehaviour
{

public float Speed;
public float JumpForce;

public bool isJumping;
public bool doubleJump;
private Rigidbody2D rig;
private Animator anim;

// Start is called before the first frame update
void Start()
{
    rig = GetComponent<Rigidbody2D>();
    anim = GetComponent<Animator>();
}

// Update is called once per frame
void Update()
{
    Move();
    Jump();
}

void Move()
{
    Vector3 movement = new Vector3(Input.GetAxis("Horizontal"), 0f, 0f);
    transform.position += movement * Time.deltaTime * Speed;

    if(Input.GetAxis("Horizontal") > 0f)

    anim.SetBool("Walk", true);
     transform.eulerAngles = new Vector3(0f,0f,0f);

    if(Input.GetAxis("Horizontal") < 0f)
    
    anim.SetBool("Walk", true);
    transform.eulerAngles = new Vector3(0f,180f,0f);

    if(Input.GetAxis("Horizontal") == 0f)
    
    anim.SetBool("Walk", false);
}

void Jump()
{
    if(Input.GetButtonDown("Jump"))
    {
        if(!isJumping)
        {
            rig.AddForce(new Vector2(0f, JumpForce), ForceMode2D.Impulse);
            doubleJump = true;
            anim.SetBool("Jump", true);
        }
        else
        {
            if(doubleJump)
            {
                rig.AddForce(new Vector2(0f, JumpForce), ForceMode2D.Impulse);
                doubleJump = false;
                anim.SetBool("Jump", false);
            }
        }
        
    }
}

void OnCollisionEnter2D(Collision2D collision)
{
    if(collision.gameObject.layer == 8)
    {
        isJumping = false;
        anim.SetBool("Jump", false);
    }
}

    void OnCollisionExit2D(Collision2D collision)
{
    if(collision.gameObject.layer == 8)
    { 
        isJumping = true;
    }
}

}

If you can help I will be grateful.

It seems that you forget some braces here :

if(Input.GetAxis("Horizontal") > 0f)
     anim.SetBool("Walk", true);
     transform.eulerAngles = new Vector3(0f,0f,0f);
if(Input.GetAxis("Horizontal") < 0f)
     anim.SetBool("Walk", true);
     transform.eulerAngles = new Vector3(0f,180f,0f);

It think that this will work :

if(Input.GetAxis("Horizontal") > 0f)
{
     anim.SetBool("Walk", true);
     transform.eulerAngles = new Vector3(0f,0f,0f);
 }
if(Input.GetAxis("Horizontal") < 0f)
{
     anim.SetBool("Walk", true);
     transform.eulerAngles = new Vector3(0f,180f,0f);
 }
