Why are my scene objects null in executables?

I put all my Scene objects in an array to build a menu from, like this:

public class LevelMenus : MonoBehaviour
{
    public Object[] levels; //my scene objects go here, from inspector.    
    private Vector2 scrollPosition;    

    public void OnGUI()
    {

        GUILayout.BeginArea(new Rect(20, 20, Screen.width - 20, Screen.height - 20));    
        scrollPosition = GUILayout.BeginScrollView(scrollPosition);            
        GUILayout.BeginVertical();

        for (int i = 0; i < levels.Length; i++)
        {
            if(GUILayout.Button(levels*.name, GUIManager.ButtonTextStyle))*
 *{*
 _Application.LoadLevel(levels*.name);*_
 _*}*_
 _*}*_ 
 _*GUILayout.EndVertical();*_
 _*GUILayout.EndScrollView();*_
 _*GUILayout.EndArea();*_
 _*}*_
_*}*_
_*```*_

I think for scene to be contained in the build you need to add them in the build settings. Also if you already have them in the build settings you don't need the array. You can load the new level with Application.LoadLevel(index) or Application.LoadLevel(name)
