LoadLevel not working. HELP, PLEASE!!!!

Guys...

What is wrong with this piece of code?

It does not wait for the button to be pressed and loads and plays another scene after 1 second

Code (CSharp):

1. using UnityEngine;
2. using System.Collections;
3.  
4. public class LangSel : MonoBehaviour {
5.  
6.     public Texture backgroundTexture;
7.     public GUIStyle ENGFlag;
8.     public GUIStyle SPAFlag;
9.     public GUIStyle CHIFlag;
10.  
11.     void OnGUI(){
12.         GUI.DrawTexture(new Rect(0,0,Screen.width,Screen.height),backgroundTexture);
13.  
14.         if (GUI.Button (new Rect(Screen.width * .05f, Screen.height * .5f, Screen.width * .25f, Screen.height * .2f), "", ENGFlag));{
15.             PlayerPrefs.SetInt("EngSpaChi", 1);
16.             Application.LoadLevel("FirstScreen");
17.         }
18.         if (GUI.Button (new Rect(Screen.width * .37f, Screen.height * .5f, Screen.width * .25f, Screen.height * .2f), "", SPAFlag));{
19.             PlayerPrefs.SetInt("EngSpaChi", 2);
20.             Application.LoadLevel("FirstScreen");
21.         }
22.         if (GUI.Button (new Rect(Screen.width * .7f, Screen.height * .5f, Screen.width * .25f, Screen.height * .2f), "", CHIFlag));{
23.             PlayerPrefs.SetInt("EngSpaChi", 3);
24.             Application.LoadLevel("FirstScreen");
25.         }
26.     }
27.  
28. }
29.  

 

Remove comma ; at the end of lines 14, 18 and 22

 

Thanks!!!!
