Roll a ball - the ball does not move??

hello,

I'm totally new to Unity and via the tutorials I'm trying to setup the first Roll a ball project. I have setup according to the tutorial the various aspects. Bu t I cannot move the ball one single inch.

below you can find the code that I have used. Whatever I doo the ball does not move.

either I'm missing something or I made an error but I seem not able to find it.

thanks for your help.

 using System.Collections;
 using System.Collections.Generic;
 using UnityEngine;
 
 public class playercontroler : MonoBehaviour {
 
     public float speed;
 
     private Rigidbody rb;
 
     void start ()
     {
         rb = GetComponent<Rigidbody>();
     }
 
     void Fixedupdate ()
     {
         float moveHorizontal = Input.GetAxis("Horizontal");
         float moveVertical = Input.GetAxis("Vertical");
 
         Vector3 movement = new Vector3(moveHorizontal, 0.0f, moveVertical);
 
         rb.AddForce(movement * speed);

Hi there! I wrote comments to the problem parts.

 // Added default value.
         public float speed = 5.0f;
 
         private Rigidbody rb;
         // Start function has to be capitalized: start() -> Start()
         void Start()
         {
             rb = GetComponent<Rigidbody>();
         }
         // FixedUpdate function has to be capitalized: Fixedupdate() -> FixedUpdate()
         void FixedUpdate()
         {
             float moveHorizontal = Input.GetAxis("Horizontal");
             float moveVertical = Input.GetAxis("Vertical");
 
             Vector3 movement = new Vector3(moveHorizontal, 0.0f, moveVertical);
 
             rb.AddForce(movement * speed);
         }

Mine wasn't working either, so I looked through my inspector to see what wasn't connecting...

Under Player Input I had no action applied. I clicked on the little dot on the side of it and found InputActions (Input Action Asset) and selected it. Now controls are applied and are working. !!!
