I need help on this movement script

Question

i need help with this script because I tried debugging it and moveHorizontal is equal to zero how can i change that here is the script below:

//setting up variables private Rigidbody2D rb2D;

 private float moveSpeed;
 private float jumpForce;
 private bool isJumping;
 private float moveHorizontal;
 private float moveVertical;


 void Start()
 {
     //defining variables
     rb2D = gameObject.GetComponent<Rigidbody2D>();
     moveSpeed = 3000000f;
     jumpForce = 60f;
     isJumping = false;

 }


 void Update()
 { //input for left right movement
     float  moveHorizontal = Input.GetAxisRaw("Horizontal");
     moveVertical = Input.GetAxisRaw("Vertical");

     Debug.Log("moveHorizontal " + moveHorizontal);
     Debug.Log("Velocity " + rb2D.velocity.x + " " + rb2D.velocity.y);

 }


 void Addforce()
 {
     //function that adds a force to rigidbody
     rb2D.AddForce(new Vector2( moveHorizontal * moveSpeed, 0f), ForceMode2D.Impulse);
    


 }


 private void FixedUpdate()
 {
     if (moveHorizontal  > 0.1f || moveHorizontal < -0.1f)
     // if moveHorizontal is greater then 0.1f or if moveHorizontal is less than -0.1f then put a force to a rigidbody
     {
         Addforce();
     }
 }

I think you should do the Rb2D initialization a little differently. Like,

     rb2D = GetComponent<RigidBody2D>();
     //We are doing this instead of gameObject.GetComponent<RigidBody2D();

I hope this Helps :-D

here is my old projects movement script i hope this helps!

 using System.Collections;
 using System.Collections.Generic;
 using UnityEngine; 
  
 public class Move2D : MonoBehaviour {
     public float movespeed = 13f;
     public bool isGrounded = false;
     
     void Update () {
         Jump();
         Vector3 movement = new Vector3(Input.GetAxis("Horizontal"), 0f, 0f);
         transform.position += movement * Time.deltaTime * movespeed;
     }

 
     void Jump(){
         if (Input.GetButtonDown("Jump") && isGrounded  == true)
         {    
             gameObject.GetComponent<Rigidbody2D>().AddForce(new Vector2(0f, 20f), ForceMode2D.Impulse);
         }
     }
 }
