Need help, paddle doesn't move when either side of screen is clicked

been trying to get back into coding to give me a hobby/motivation during these times and I was following this tutorial on how to make a simple android game in unity in 2020 (

)
everything was going perfect until the 31-minute mark where he clicks the screen and the paddle moves to where he clicks but when I do it the paddle doesn't respond at all, I've watched the footage multiple times now and still can't see what I did wrong, can anyone help?

Code (CSharp):

1. using System.Collections;
2. using System.Collections.Generic;
3. using UnityEngine;
4.  
5. public class Paddle : MonoBehaviour
6. {
7.  
8.     Rigidbody2D rb;
9.     public float moveSpeed;
10.  
11.     private void Awake()
12.     {
13.         rb = GetComponent<Rigidbody2D>();
14.     }
15.  
16.     // Start is called before the first frame update
17.     void Start()
18.     {
19.  
20.     }
21.  
22.     // Update is called once per frame
23.     void Update()
24.     {
25.  
26.     }
27.  
28.     private void Fixedupdate()
29.     {
30.         TouchMove();
31.     }
32.  
33.     void TouchMove()
34.     {
35.  
36.         if (Input.GetMouseButton(0))
37.         {
38.             Vector2 touchPos = Camera.main.ScreenToWorldPoint(Input.mousePosition);
39.  
40.             if (touchPos.x < 0)
41.             {
42.                 rb.velocity = Vector2.left * moveSpeed;
43.  
44.             }
45.             else
46.             {
47.                 rb.velocity = Vector2.right * moveSpeed;
48.  
49.             }
50.  
51.         }
52.         else
53.         {
54.             rb.velocity = Vector2.zero;
55.         }
56.    
57.     }
58.  
59. }
60.  

 

Did you set your move speed to something > 0?

 

Yup, set it to 8, is there like a way I can export my project so far so you guys can see?
