Trying to make a main menu thing to make different SCENES appear....

Please correct my script if possible..... I don't know where I went wrong.... I was following a youtube tutorial and now I'm stuck on not being able to drag the new script written into a Scene01Button button I made... Please help...

Code (CSharp):

1. using System.Collections;
2. using System.Collections.Generic;
3. using UnityEngine;
4. using UnityEngine.SceneManagement;
5.  
6. public class SceneSelectScript: MonoBehaviour{
7.  
8.    public void selectScene() {
9.         switch (this.gameObject.name) {
10.             case "Scene01Button":
11.                 SceneManager.LoadScene.("Scene01");
12.                 break;
13.             case "Scene02Button":
14.                 SceneManager.LoadScene. ("Scene02");
15.                 break;
16.             case "Scene03Button":
17.                 SceneManager.LoadScene. ("Scene03");
18.                 break;
19.         }
20.     }
21. }
