Issues with making a "Quest Dialogue" box

Graphics Shaders & Materials

Hi, I’m trying to make a dialogue box similar to the quest boxes in WoW, and I’ve got it working almost perfectly, but not quite.

Two issues:
1. The scroll bar doesn’t work. This is the first time I’ve ever tried to make anything with a scroll bar, and I’m a little lost. Basically I just need to know how to attach the scroll bar to the text area so it can control it.
2. The player can highlight the text, which I don’t want, but I couldn’t figure out how to get the text to display except by using a TextArea, which inherently allows the user to highlight the text.

My code:

var highlighted = false;	// Used to determine whether or not NPC is highlighted
var talk = false;		// Used to determine whether or not NPC is talking
var title : String;		// Title of the textbox for the NPC dialogue
var dialogue : String;		// The dialogue of the NPC (i.e. what the NPC says)
var asset : TextAsset;		// Points to the text file that contains the NPC dialogue 



// Changes the color of the material while the mouse is over the mesh
function OnMouseOver ()
	{
		renderer.material.color = Color(1.5, 1.5, 1.5);
		highlighted = true;
	}
	
function OnMouseExit ()
	{
		renderer.material.color  = Color(1, 1, 1);
		highlighted = false;
	}

// Detect left mouse click and print it in the debug log.
function OnGUI()
{
	var click : Event = Event.current;


	if(click.button == 0  click.isMouse)
	{
		if (highlighted == true)
		{
			//Debug.Log("Left Click");
			talk = true;
		}
	}

	if (talk == true)
	{ //(horizontal position, vertical position, horizontal size, vertical size)
		GUI.Box(Rect(50,50,325,400),title);
		if (GUI.Button(Rect(350,53,22,15),"x"))
		{
			//Debug.Log("Closed the dialogue box.");
			talk = false;
		}

		//(h-position, v-position, h-size, v-size)
		GUI.TextArea(Rect(60,75,290,345),dialogue);

		dialogue = asset.text;
		
		var vSbarValue : float;
		
		//(h-position, v-position, h-size, v-size)
		vSbarValue = GUI.VerticalScrollbar(Rect (354, 76, 100, 343), vSbarValue, 1.0, 10.0, 0.0);


		if (GUI.Button(Rect(315,425,55,20),"Accept"))
		{
			//Debug.Log("Accepted the quest.");
			talk = false;
		}
		
		if (GUI.Button(Rect(255,425,57,20),"Decline"))
		{
			//Debug.Log("Declined the quest.");
			talk = false;
		}
	}
}

No one knows how to make a scrollbar?

EDIT: I figured it out on my own.
