Error with multiplayer script (not done)

So i get this 3 errors :

  1. Assets/Scripts/MenuManager.cs(54,91): error CS0103: The name `maxusers’ does not exist in the current context

  2. Assets/Scripts/MenuManager.cs(54,53): error CS1502: The best overloaded method match for `MultiplayerManager.StartServer(string, string, int)’ has some invalid arguments

  3. Assets/Scripts/MenuManager.cs(54,53): error CS1503: Argument #3' cannot convert object’ expression to type `int’

This is the script :
using UnityEngine;
using System.Collections;

public class MenuManager : MonoBehaviour 
{
    public string CurrentMenu;
	
	public string MatchName = "";
	public string MatchPassword = "";
	public  int MatchMaxPlayers = 32;
	
	
	void Start ()
	{
	    CurrentMenu = "Main";
	}
	
	void OnGUI()
	{
	    if (CurrentMenu == "Main")
			Menu_Main();
		if (CurrentMenu == "Lobby")
			Menu_Lobby();
		if (CurrentMenu == "Host")
			Menu_HostGame();
	}

	public void NavigateTo(string nextmenu)
	{
	    CurrentMenu = nextmenu;
	}
    
	private void Menu_Main()
	{
		if (GUI.Button(new Rect(10,10,200,50), "Host Game"))
		{   
			NavigateTo("Host");
		}
		
			GUI.Label (new Rect(220,10,130,30), "Player Name");
		MultiplayerManager.instance.PlayerName = GUI.TextField (new Rect(400,10,200,30),MultiplayerManager.instance.PlayerName);
	}
	
	private void Menu_HostGame()
	{
		//Button Host Game
		if (GUI.Button(new Rect(10,10,200,50), "Back"))
		{   
			NavigateTo("Main");
		}
		
		if (GUI.Button(new Rect(10,60,200,50), "Start Server"))
		{
			MultiplayerManager.instance.StartServer(MatchName, MatchPassword, maxusers);
	    }
		
		GUI.Label (new Rect(220,10,130,30), "Match Name");
		MatchName = GUI.TextField (new Rect(400,10,200,30),MatchName);
		
		GUI.Label (new Rect(220,50,130,30), "Match Password");
		MatchPassword = GUI.PasswordField(new Rect(400,50,200,30),MatchPassword, '*');
		
		GUI.Label (new Rect(220,90,130,30), "Match Max Players");
		GUI.Label (new Rect(400,90,200,30), MatchMaxPlayers.ToString());
		MatchMaxPlayers = Mathf.Clamp(MatchMaxPlayers, 8, 32);
		
		if (GUI.Button(new Rect(425,90,25,30), "+"))
			MatchMaxPlayers += 2;
		if (GUI.Button(new Rect(450,90,25,30), "-"))
			MatchMaxPlayers -= 2;
	}
	
	private void Menu_Lobby()
	{
	
	}
}

the problem is this line:

MultiplayerManager.instance.StartServer(MatchName, MatchPassword, maxusers);

the third argument “maxusers” does not seem to have been declared anywhere, did you perhaps mean MatchMaxPlayers?

MultiplayerManager.instance.StartServer(MatchName, MatchPassword, MatchMaxPlayers);
