unity is saying the build settings has not been added even though it has. help??

it isnt letting me send it seperately. so ive copied it and the script and the line with the asterisks on either side of it is line 36.

using UnityEngine; using UnityEngine.UI; using System.Collections;

public class menuscriptcchh : $$anonymous$$onoBehaviour {

 public Canvas quit$$anonymous$$enu;
 public Button startText;
 public Button exitText;
 // Use this for initialization
 void Start()
 {
     quit$$anonymous$$enu = quit$$anonymous$$enu.GetComponent<Canvas>();
     startText = startText.GetComponent<Button>();
     exitText = exitText.GetComponent<Button>();
     quit$$anonymous$$enu.enabled = false;
 }

 // Update is called once per frame
 public void ExitPress()
 {
     quit$$anonymous$$enu.enabled = true;
     startText.enabled = false;
     exitText.enabled = false;

 }
 public void NoPress()
 {
     quit$$anonymous$$enu.enabled = false;
     startText.enabled = true;
     exitText.enabled = true;
 }
 public void StartLevel()
 {
     **Application.LoadLevel(1);**
 }
 public void ExitGame()
 {
     Application.Quit();
 }

}.

If you have other scenes and you are not able to drag them in the build setting, try to close unity and reopen it. Unity sometimes glitches.
