Error: Need help

I am trying to make a script to open a URL when pressed.
I made a GUI Texture, (Not sure if that can be used as a button or not.)
I have 2 errors

(9,46): error CS0119: Expression denotes a type', where a variable’, value' or method group’ was expected
(10,28): error CS0119: Expression denotes a type', where a variable’, value' or method group’ was expected

I know Im supposed to have var. but not sure what.
This is the script so far
Any help will be appreciated

using UnityEngine;
using System.Collections;

public class info : MonoBehaviour {
	
	// Use this for initialization
	void Start () {
	//Draw info button
			Texture infoButton = GUITexture;
			if(GUITexture(new GUIContent(infoButton),"trans_button"))
			{
				
				Application.OpenURL("http://www.Facebook.com/MSheriGames");
			}
	}
	
	// Update is called once per frame
	void Update () {
	
	}
}

You didn’t make your GUITexture properly.
http://docs.unity3d.com/Documentation/ScriptReference/GUITexture.html

If I’m not wrong, GUITexture is a component. So what you want to do is create a GUITexture by using AddComponent. However, if you’re doing a button, I’d recommend you to use GUI.Button or create a cube or gameobject in the game with a collider and define the function OnMouseUpAsButton and do whatever you want.

You are a life saver, I love that you always give me links to info.!!!
quick question how do I give a thumbsup on answers?
