I can't seem to use my scrollBar? c#

So, I decided I was going to test out my loot window, but for some reason when i click inside the scroll part, it will not scroll down at all!

here is the code:

using UnityEngine;
using System.Collections;
using System.Collections.Generic;

public class LootWindow : MonoBehaviour {
	public GUIStyle EButton; // 20 by 20
	public GUIStyle LootWindowGUI;
	
	//LootWindow orientated
	public const int LootWindowID = 0;
	public Rect LootWindowRect = new Rect(0,0,0,0);
	public List<ItemDataBase> LootItems;
	
	public Vector2 WindowSlider = Vector2.zero;
	

	void Start () {
	LootItems = new List<ItemDataBase>();
	Populate();
	}
	
	void OnGUI(){
	LootWindowRect = GUI.Window(LootWindowID,new Rect(Screen.width/2-100,Screen.height/2-200,200,300),LootWindowOpen,"Loot Window",LootWindowGUI);
		
		
	}
	
	public void LootWindowOpen(int id){
	WindowSlider = GUI.BeginScrollView( new Rect(10,45,LootWindowRect.width - 10, 300),WindowSlider,new Rect(15,18,LootItems.Count *60,10 *60));
	for(int i=0; i < 3; i++){
		for( int y =0; y < 10; y++){	
		GUI.Button(new Rect(10+(i * 60),20 +(y * 60),60,60),"T" + (i + y * 5));		
	}
	}
	GUI.EndScrollView();
		
	}
			
	public void Populate(){
	for(int i=0; i < 20; i++){
		LootItems.Add( new ItemDataBase());	
		}
		
	}
}

Sorry guys I figured out the issue, I had another window with the same ID. sorry for wasting your time, a moderator can remove this post if he or she wants to.

Many thanks.
