I'm trying out the PlayerPrefs Class with my code for a bulletin board now and I must be doing something wrong. I'm trying to load previously saved strings with OnLevelWasLoaded and then save new strings when the submit button is pressed. I can't seem to get it to work. I'd really appreciate it if someone could take a look at this.

  var stringToEdit: String = "What's The News?";
var customSkin: GUISkin;
var maxMessage = 10;
var messagesTyped: String[];
var messageSpacing: float = 10;
var maxChar : int = 30;
var scrollPosition : Vector2 = Vector2.zero;
var messageAlert : String = "New Message From ";
var nameField: String = "Name";
private var msgCounter: int;

function Start()
{
    maxMessage--;
    messagesTyped = new String[maxMessage];

}

function OnLevelWasLoaded(){
    //get input
    loadLevel();
}

function loadLevel(){
    if(PlayerPrefs.HasKey(nameField+ stringToEdit)){
    Application.LoadLevel(PlayerPrefs.GetString(nameField, stringToEdit));
    }   
}

function OnGUI()
{
    GUI.skin = customSkin; 

    stringToEdit = GUI.TextField(Rect(270, 100, 450, 80), stringToEdit, maxChar);
    nameField = GUI.TextField(Rect(80, 100, 180, 30), nameField, maxChar);
    if (GUI.Button(Rect(730, 100, 60, 30), "Submit"))
    {
        SubmitMsg( messageAlert + nameField + ":  " + stringToEdit);
        saveMessage();

    }
    var x: float = 270;
    var y: float = 180;
    for (var i: int;
    i < messagesTyped.length;
    i++)
    {
        y += messageSpacing;
        //print("Here");
        GUI.Label(Rect(x, y, 500, 60), messagesTyped[i]);
    }
    }
function SubmitMsg(submittedMsg: String)
{
    if (msgCounter == maxMessage)
    {
        msgCounter = 0;
    }
    messagesTyped[msgCounter] = submittedMsg;
    print(messagesTyped[0]);
    msgCounter++;
}

function saveMessage(){
PlayerPrefs.SetString(nameField, stringToEdit);
print("saved");
}
