Same Scene - Different Button in One Script

Hi; first of all sorry for my english.

i have two button in my scene. button 1 name "settings" and button 2 name "stats". i have two scenes also same names. i want to go settings scene when i touch settings button and i want to go stats scene when touch stats button. so how can i do it in one script file with c#.

(i can do two scripts like this:)

using UnityEngine; using System.Collections;

public class nasilOynanir : MonoBehaviour {

 public void nasilOynanir1()
 {
     if (Application.loadedLevelName == "anamenu")
         Application.LoadLevel ("stats");

     if (Application.loadedLevelName == "stats")
         Application.LoadLevel ("anamenu");
 }

}
