After adding script for rotation to look up down, look left right stopped working,After writing code for the rotation for looking up down, looking right left stopped

using System.Collections; using System.Collections.Generic; using UnityEngine;

public class MouseLook : MonoBehaviour { public float MouseSensitivity = 100; public Transform PlayerBody;

 //This i created for up down
 float xRotation = 0f;
 void Start()
 {
     Cursor.lockState = CursorLockMode.Locked;
 }

 // Update is called once per frame
 void Update()
 {
     float mouseX = Input.GetAxis("Mouse X") * MouseSensitivity * Time.deltaTime;
     float mouseY = Input.GetAxis("Mouse Y") * MouseSensitivity * Time.deltaTime;

     PlayerBody.Rotate(Vector3.up * mouseX);

     
     
     
     
     //This is the script for up down
     xRotation -= mouseY;
     xRotation = Mathf.Clamp(xRotation, -90f, 90f);
     transform.localRotation = Quaternion.Euler(xRotation, mouseX, 0f);
     
 }
