Unable To Move Vertical ingame

This is my Code
using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class PlayerController : MonoBehaviour
{



public float speed = 18;

private Rigidbody2D rig;

Vector2 movement;
// Use this for initialization
void Start()
{
rig = GetComponent<Rigidbody2D>();

}

// Update is called once per frame
void Update()
{
float hAxis = Input.GetAxis("Horizontal");
float vAxis = Input.GetAxis("Vertical");

Vector3 movement = new Vector3(hAxis, 0, vAxis) * speed * Time.deltaTime;

rig.MovePosition(transform.position + movement);

}
}
I checked most things but now I just want to know if it's an error with the code
