what im trying to do is add a save load feature into my game, i want to save the location fo all the cubes in the game. i'm using the arrayprefs script from http://www.unifycommunity.com/wiki/index.php?title=ArrayPrefs. i have my save function working but i cant figure out how to load the game from my main menu scene. Here is my load function. this script is in my main menu.

function loadGame()
    {
        Application.LoadLevel("start");
        for (i=0 ; i < button2.cubes.length ; i++)
        {
        curName = button2.cubes[i];
        var go = Instantiate(cube2, PlayerPrefsX.GetVector3(curName), Quaternion.identity);
            go.name = curName;
            Debug.Log("lOADED!");
        }

    }

button2 is my saving script is in my first level, here is what the save function looks like for that level.

static var cubes = new Array();
var cubeCount = 0;
function Update()
{
if (Input.GetMouseButtonDown(0))
            {


            var go = Instantiate(cube2, transform.position, Quaternion.identity) as GameObject;
            go.name = "cube"+cubeCount;
            cubes.Add("cube"+cubeCount);
            cubeCount++;
            }   

if(Input.GetKey("m"))
            {
            saveGame();
            Debug.Log("saved");
            }

}

function saveGame()
    {


        for (i=0 ; i < cubes.length - 1 ; i++)
        {

        curName = cubes[i];
        PlayerPrefsX.SetVector3( curName, GameObject.Find(curName).transform.position);
        }

What am i doing worng?

EDIT**

here are my new scripts.

This is my CubeManager script that is attached to empty gameobjects in the first level and the main menu.

static var cubes = new List.<Transform>();
var cube2 : GameObject;

function CreateCube(position : Vector3) : Transform
{
    var cube : GameObject = Instantiate(cube2, position, Quaternion.identity);
    cube.name = "cube" + cubes.Count;
    cubes.Add(cube.transform);
}

function SaveCubes()
{
    PlayerPrefs.SetInt("button2.cubeCount", cubes.Count);
    for(var T : Transform in cubes)
    {
        PlayerPrefsX.SetVector3(T.name,T.position);
    }
}

function LoadCubes()
{

    Application.LoadLevel("start");
    cubes.Clear();
    var cubeCount = PlayerPrefs.GetInt("button2.cubeCount");
    for(var i = 0; i < cubeCount; i++)
    {
        CreateCube(PlayerPrefsX.GetVector3("cube"+i));
    }

Here is my script that is in my first level to save the cubes.

function Update()
    {

    var managerScript : CubeManager = FindObjectOfType(CubeManager);

        if (Input.GetMouseButtonDown(0))
            {managerScript.CreateCube(transform.position);
            }   
        if(Input.GetKey("m"))
            {

            managerScript.SaveCubes();
            Debug.Log("saved");
            }
}

Here is my script that is attached to my load button on the main menu to call the load function:

function OnMouseUp()
{

var managerScript : CubeManager = FindObjectOfType(CubeManager);
    if(isQuit)
        Application.Quit();
    else
        {

        managerScript.LoadCubes();

        }


}
