Question Need help with main menu error fast

This error message keeps coming up when I click the play button on my main menu.

Scene 'SceneManager.GetActiveScene().buildIndex + 1' couldn't be loaded because it has not been added to the build settings or the AssetBundle has not been loaded.
To add a scene to the build settings use the menu File->Build Settings...
UnityEngine.SceneManagement.SceneManager:LoadScene (string)
MainMenuPlayGame () (at Assets/MainMenu.cs:10)
UnityEngine.EventSystems.EventSystem:Update ()

I have added the main menu scene and game scene to the build settings and it keeps coming.

I can post code too if needed.

This is my first project so please bear with me.

 

It kinda seems like you did something like:

Code (CSharp):

1. SceneManager.Load("SceneManager.GetActiveScene().buildIndex + 1");

Instead of the correct:

Code (CSharp):

1. SceneManager.Load(SceneManager.GetActiveScene().buildIndex + 1);

Is that right?

 

Code (CSharp):

1. using System.Collections;
2. using System.Collections.Generic;
3. using UnityEngine;
4. using UnityEngine.SceneManagement;
5.  
6. public class MainMenu : MonoBehaviour
7. {
8.     public void PlayGame ()
9.     {
10.         SceneManager.LoadScene("SceneManager.GetActiveScene().buildIndex + 1");
11.  
12.     }
13.  
14.     public void QuitGame ()
15.     {
16.         Debug.Log("QUIT");
17.         Application.Quit();
18.     }
19. }
20.  

 

So... did you try fixing it how PraetorBlue suggested?
