Hi guys i have a problem with my script.I get an error that my script take arguments.

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

public class MainMenu : MonoBehaviour {
	public static MainMenu instance;
	public string CurMenu;
	public List<Buyable> Characters = new List<Buyable> ();


	public Texture2D P;
	public Texture2D S;
	public Texture2D Set;


	void Awake()
	{
		CurMenu = "Main";
		instance = this;
	}
	// Use this for initialization
	void ToMenu(string menu){
		CurMenu = menu;
	}
	void OnGUI(){
		if (CurMenu == "Play")
			Play();
		if (CurMenu == "Shop")
			Shop();
		if (CurMenu == "Settings")
			Settings();
		if (CurMenu == "Main")
			Main();
		
	}

	private void Main()
	{
		if (GUI.Button (new Rect (100,150, 150, 100), P)) {
			ToMenu ("Play");
		}
		
		if (GUI.Button (new Rect (100,250, 150, 20), "Play")) {
			ToMenu ("Play");
		}
		if (GUI.Button (new Rect (400,150, 150, 100), S)) {
			ToMenu ("Shop");
		}
		
		if (GUI.Button (new Rect (400,250, 150, 20), "Shop")) {
			ToMenu ("Shop");
		}
		if (GUI.Button (new Rect (700,150, 150, 100), Set)) {
			ToMenu ("Settings");
		}
		
		if (GUI.Button (new Rect (700,250, 150, 20), "Settings")) {
			ToMenu ("Settings");
		}
	}






	private void Menu()
	{
		if(GUI.Button(new Rect(0,375,128,32),"Back")){
			ToMenu("Main");
		}
	}

	private void Shop(Rect position, Buyable buyable)
	{
	if(GUI.Button(new Rect(0,375,128,32),"Back"))
	{
	ToMenu("Main");
	}
		{
			GUIContent iconButtonLabel = new GUIContent(buyable.CharTexture, "Some Tooltip");
			GUIContent textButtonLabel = new GUIContent(buyable.name, "Another Tooltip");
			
			GUILayout.BeginArea(position);
			
			if (GUILayout.Button(iconButtonLabel))
				print ("you clicked the icon");
			
			if (GUILayout.Button(textButtonLabel))
				print ("you clicked the text button");
			
			GUILayout.EndArea();
		}

	}
	private void Settings()
	{
		if(GUI.Button(new Rect(0,375,128,32),"Back")){
			ToMenu("Main");
		}
	}
	private void Play()
	{
		if(GUI.Button(new Rect(0,375,128,32),"Back")){
			ToMenu("Main");
		}
	}
}
	[System.Serializable]
	public class Buyable
	{
		public string name;
		public Texture2D CharTexture;
		public int Cost;
	}

I know im supposed to be adding something on

if (CurMenu == "Shop")
    			Shop();

But i have no idea what,i tried adding lots of things on Shop(); but all errors.Thanks

Your Shop actually takes two values as argument since you have defined your function as:

private void Shop(Rect position, Buyable buyable) {

which means whenever you call your Shop function it should contain two values that will be of type Rect and Buyable inside it like:

Shop(rectangle, buyableItem);

where variable rectangle is of type Rect and variable buyableItem is of type Buyable.
