I just started Unity and I followed a Video to make a character controller but it doesn’t work

This is my code for it:

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

public class Controller : MonoBehaviour
{ 
    private CharacterController characterController;

    public float Speed = 5f;
    // Start is called before the first frame update
    void Start()
    {
       characterController = GetComponent<CharacterController>();
    }

    // Update is called once per frame
    void Update()
    {
        Vector3 move = new Vector3(Input.GetAxis("Horisantal"), 0, Input.GetAxis("Vertical"));

        characterController.Move(move * Time.deltaTime * Speed);
    }
}

Hi. Everything looks fine, except you’ve spelled “horizontal” wrong. This should fix it.
