Having problem with GUI.Scrollview in a GUI.window, Scrollbar not showing up.

Unity Engine

I am trying to make a list of buttons that show up in a window and are scrollable. i have the window and buttons show up fine, but the scrollbar is not showing up and i can not scroll the buttons.

public Vector2 scrollPostion = Vector2.zero;

...

void OnGUI()
	{
		if (listdownloaded) 
		{
			StopCoroutine("getlevels");
			//GUI.Box(new Rect(Screen.width*0.1f,Screen.height*0.1f, Screen.width*0.8f, Screen.height*0.8f), "Custom Levels");
			GUI.Window(1, new Rect(Screen.width*0.1f,Screen.height*0.1f, Screen.width*0.8f, Screen.height*0.8f), customlevelbuttonlist, "Custom Levels");
		}
		else if(loadCustom)
		{
			...
		}

	}

	void customlevelbuttonlist(int windowID)
	{
		float count=0;
		scrollPostion=GUI.BeginScrollView(new Rect(Screen.width*0.05f, Screen.height*0.05f, Screen.width*0.75f, Screen.height*0.7f), scrollPostion, new Rect(0,0, Screen.width*0.7f, Screen.height*0.65f));
		foreach(CustomLevel level in CustomLevels)
		{
			if(GUI.Button(new Rect(0, buttonheight*count, Screen.width*0.7f, 45), level.Name))
			{
				Commons.levelLocation=CustomLevels[(int)count].location;
				updatepercent();
				UpDateAchievements();
				Application.LoadLevel(gotoSceneIndex);
				Debug.Log(CustomLevels[(int)count].location.ToString());
				Debug.Log(SceneIndex);
			}
			count++;
		}
		GUI.EndScrollView();
		//GUI.DragWindow();
	}

i have never worked with scrollviews before so any help i can get would be very appreciated.

Try the example in the documentation, probably you need a larger viewRect:

Or try GUILayout that automatically calculates the rects.

the GUILayout worked perfectly thank you so much.
