Build index is trying to fond scene 2 even though I think I'm telling it to find scene 1

I’m trying to create a main menu and change from scene0 to scene 1, but for some reason, it is trying to load scene 2 and I get the following error message:

Scene with build index: 2 couldn’t be loaded because it has not been added to the build settings.
To add a scene to the build settings use the menu File->Build Settings…
UnityEngine.SceneManagement.SceneManager:LoadScene (int)
MainMenu:PlayGame () (at Assets/Scripts/MainMenu.cs:10)
UnityEngine.EventSystems.EventSystem:Update ()

I have two scenes in the build editor, 0 and 1 and I don’t know why it is trying to find a scene 2.

Here is my code:

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

public class MainMenu : MonoBehaviour
{
public void PlayGame()
    {
        SceneManager.LoadScene(SceneManager.GetActiveScene().buildIndex + 1);
    }
}

You have to go into the build settings in the unity editor and add in the scene to the build.

NVM fixed it, just had my menu and game on the same scene
