Hi! Plz help, I have an Error: Assets/myGUI.cs(11,22): error CS0246: The type or namespace name `Item' could not be found. Are you missing a using directive or an assembly reference?

Here the script: using UnityEngine; using System.Collections; using System.Collections.Generic;

public class myGUI : MonoBehaviour { public float lootWindowHeight = 90;

public float buttonWidth = 40;
public float buttonHeight = 40;

private List<Item> _lootItems;
private float _offset = 10;
private const int LOOT_WINDOW_ID = 0;
private Rect _lootWindowRect = new Rect(0,0,0,0);

// Use this for initialization
void Start () {
    _lootItems = new List<Item>();

    Populate();
}

// Update is called once per frame
void Update () {

}

void OnGUI() {
    _lootWindowRect = GUI.Window(LOOT_WINDOW_ID, new Rect(_offset, Screen.height - (_offset + lootWindowHeight), Screen.width - (_offset * 2), lootWindowHeight), LootWindow, "Loot Window");
}

private void LootWindow(int id) {
    for(int cnt = 0; cnt < _lootItems.Count; cnt++) {
       GUI.Button(new Rect(buttonWidth * cnt, 0, buttonWidth, buttonHeight), cnt.ToString());
    }
}

private void Populate() {
    for(int cnt = 0; cnt < 25; cnt++)
       _lootItems.Add(new Item());
}

}
