C# script help?

I get a total of 9 errors from this script. Here is an image of the errors I got:

(And here is the script which has these errors, may someone please fix it?)

using UnityEngine;
using System.Collections;

public class MenuManager : MonoBehaviour
{
public string CurrentMenu;

public string MatchName = "";
public string MatchPassword = "";
public int MaxmatchPlayers = 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");
	}
}		

private void Menu_HostGame()
{
	//Buttons Host Game
	if(GUI.Button(new Rect(10, 10, 50, 50), "back"))
	{
		NavigateTo("Main");
	}
	
	if(GUI.Button(new Rect(60, 10, 200, 50), "Start Server"))
	{
		
	}
	
	GUI.Label(new Rect(300, 10, 130, 30), "Match Name");
	MatchName = GUI.TextField(new Rect(400, 10,200, 30), MatchName);
	
	GUI.Label(new Rect(300, 50, 130, 30), "Match Password");
	MatchPassword = GUI.PasswordField(new Rect(400, 50, 200, 30), MatchPassword, '*');
	
	GUI.Label(new Rect(300, 90, 130, 30), "Match Max Players");
	string maxuser = GUI.TextField(new Rect(400, 90, 200, 30), MatchMaxPlayers.ToString());
	MatchMaxPlayers = Interpolator.Parse(maxuser);
	MatchMaxPlayers = Mathf.Clamp(MatchMaxPlayers, 8, 32); 
	
}

private void Menu_Lobby()
{
	
}

}

Whenever you see “cannot convert ‘object’”, look to see what variable you have not declared, or some sort of issue with your declaration. In this case, you declare the variable on line 3 as:

public int MaxmatchPlayers = 32;

But your actual use (and I’m assuming this is the variable you wanted to use) is:

MatchMaxPlayers = Mathf.Clamp(MatchMaxPlayers, 8, 32); 

Note the difference in the two names.

MaxMatchPlayers is mispelled on declaration (at the top)

GUI.TextField has too many or too few parameters in the overload

GUI.TextField is not a string

Mathf has too many or too few parameters in the overload

You can’t use a GameObject as a float.

Look at the rest of the overload error to see what the function accepts and how many arguments you’re passing.
