Why is my unity2d character not moving?

Question

Unity

The character does not respond to movements, although the code was written, and also gives the following error:

Here is the code:

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

public class Player : MonoBehaviour
{
    Rigidbody2D rb;
    public float speed;

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

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

    void FixedUpdate()
    {
        rb.velocity = new Vector2(Input.GetAxis("Horrizontal") * speed, rb.velocity.y);
    }
}

No need to produce questions. Although this one is formatted according to the rules, so...
You don't have the axes set up. To set up the axes - in the Edit->Settings->Input unit (it's in the menu).
But in general - it seems that there is a horizontal axis by default - it only remains to write it correctly - you have a typo in the word Horrizontal - it should contain one r.
