Need to use 2 different language scripts.

Hi again, I’m trying to use these 2 scripts:

Javascript one:

var skinGUI : GUISkin;
var logoTexture : Texture2D;

var LoadingScreen : LoadingScreen = null;

function Start() {
    LoadingScreen = new LoadingScreen();
}

function theFirstMenu() {
    GUI.BeginGroup(Rect(Screen.width / 2 - 150, Screen.height / 2, 300, 200));
    GUI.Box(Rect(0, 0, 300, 100), "");
   
    if(GUI.Button(Rect(55, 18, 180, 40), "Start game")) {
     LoadingScreen.Load("Main Scene");
    }
    if(GUI.Button(Rect(55, 52, 180, 40), "Quit")) {
     Application.Quit();
    }
   
    GUI.EndGroup();
}

function OnGUI () {
    GUI.skin = skinGUI;
    
    theFirstMenu();
}

C Sharp one:

using UnityEngine;

public class LoadingScreen : MonoBehaviour
{
    public Texture2D texture;
    static LoadingScreen instance;

    void Awake()
    {
        if (instance)
        {
            Destroy(gameObject);
            return;
        }
        instance = this;    
        gameObject.AddComponent().enabled = false;
        guiTexture.texture = texture;
        transform.position = new Vector3(0.5f, 0.5f, 0.0f);
        DontDestroyOnLoad(this); 
    }

    public static void Load(int index)
    {
        if (NoInstance()) return;
        instance.guiTexture.enabled = true;
        Application.LoadLevel(index);
        instance.guiTexture.enabled = false;
    }

    public static void Load(string name)
    {
        if (NoInstance()) return;
        instance.guiTexture.enabled = true;
        Application.LoadLevel(name);
        instance.guiTexture.enabled = false;
    }

    static bool NoInstance()
    {
        if (!instance)
            Debug.LogError("Loading Screen is not existing in scene.");
        return instance;
    }
}

But the console says:
“Assets/MainMenu/MainMenuScript.js(4,21): BCE0018: The name ‘LoadingScreen’ does not denote a valid type (‘not found’).”

Obs.: The 2 scripts are in the same folder.

I don’t explain it again. This really has been asked too often…

Here’s the page you need:
