Change Scene script and it's not working - how can I fix it ?

With this code I shoud schange the scene, but forsome reason I have no idea it's not working.
Unity save as scene01, scene02 and scene03.

Must I have camera in every scene (for that I don't have) ?
In tutorial showe me that they diddn't make more or add it to new scene.

Code (CSharp):

1.  
2. public class ScangeScene : MonoBehaviour
3. {
4.  
5.     //public void ChangeToScene (int sceneToChangeTo)
6.     public void ChangeToScene(string sceneToChangeTo)
7.     {
8.         Application.LoadLevel(sceneToChangeTo);
9.     }
10. }

Depending on the version of Unity you're using:

https://docs.unity3d.com/ScriptReference/Application.LoadLevel.html

 

Have you added your scenes in the Build Settings?

https://docs.unity3d.com/Manual/BuildSettings.html

 

sceneToChangeTo, can't find it so I use name.
Squad
_Manager
error msg, only if am using more than one scene.

To LurkingNinjaDev: I have unity 2018..2.15f.1 personal.
To LurkingNinjaDev: Yup, but not saved the build, am just clicked out. I try to save but only asking to load in a folder.

Code (CSharp):

1.  
2. using UnityEngine;
3. using UnityEngine.SceneManagement;
4.  
5. public class ChangeScene : MonoBehaviour
6. {
7.     public void ChangeToScene(string sceneToChangeTo)
8.     {
9.         SceneManager.LoadScene(sceneToChangeTo);
10.     }
11. }
12.  

Any other idea how/what I can use ?

I found out that the button don't get the message.
I used "Debug.Log("You Clicked the Button");" and it not respond.


Ok, I had to make it all from scratch and at last it worked.
I can't say why it worked now or not the first one.

This is now solved.
