character not moving, though code seems to be right

so im trying to make a simple roller ball following a tutorial on youtube, my code seems to be the same as his, but my character just wont move. im unsure if this is due to my input settings but WASD and the arrow keys do nothing.

any suggestions?

 using System.Collections;
 using System.Collections.Generic;
 using UnityEngine;
 
 public class BallMovement : MonoBehaviour
 {
 
     public float ballSpeed;
   
 
     // Start is called before the first frame update
     void Start()
     {
         
     }
 
     // Update is called once per frame
     void Update()
     {
         float xSpeed = Input.GetAxis("horizontal");
         float ySpeed = Input.GetAxis("vertical");
 
         Rigidbody rb = GetComponent<Rigidbody>();
 
         rb.AddTorque(new Vector3(xSpeed,0,ySpeed) * ballSpeed * Time.deltaTime);
     }
 }
