What is wrong with this script?

var savedTForm00 : Transform; 
private var Scene : String;




function SaveIt00(){///==SAVEIT==/// 
    PlayerPrefs.SetString(Scene);
} 

function LoadIt00(){///==LOADIT==///  
    PlayerPrefs.GetString(Scene);
}
var autoLoad : boolean;

function Start() {
  if(autoLoad==true) {
  LoadIt00();
  }
}
function Update() {
  if(Input.GetKey("m")) {
  SaveIt00();
  }
  if((Input.GetKey("b"))&&(autoLoad==false)) {
  LoadIt00();
  }
}
