Cannot Implicitly convert to bool problem?

I’m working on the main menu for my new IOS game and have run into a snag. I’m getting the error message:

Assets/SpaceCombatRPG-IOS Framework/Scripts/Non-Completed/MainMenu.cs(42,22): error CS0029: Cannot implicitly convert type MainMenu.Page' to bool’

And yes, I do know what it means, but I cannot figure out the correct way to fix it. And I do not have any boolean variables which is the odd part. I’m guessing the problem seems to be with the way I am storing variables from my enumeration? Here’s the code:

using UnityEngine;
using System.Collections;

public class MainMenu : MonoBehaviour {
	private enum Page {
		NewGame = 0,
		Resume = 1,
		LoadGame = 2,
		Options = 3,
		MoreGames = 4,
		GameGuide = 5,
		Addons = 6,
		GameCenter = 7,
		MainMenu = 8
	}

	private Page _currentPage;

	public Texture2D gameNameTexture;
	public Texture2D defaultButton;
	public Texture2D addonsButton;
	public Texture2D moreGamesButton;
	public Texture2D gameGuideButton;
	public Texture2D gameCenterButton;
	

	void Start() {
		_currentPage = Page.MainMenu;
	}

	void OnGUI() {
		if(_currentPage = Page.MainMenu)
			DisplayMainMenu();
		else if(_currentPage = Page.NewGame)
			DisplayNewGameMenu();
		else if(_currentPage = Page.Resume)
			DisplayResumeMenu();
		else if(_currentPage = Page.LoadGame)
			DisplayLoadGameMenu();
		else if(_currentPage = Page.Options)
			DisplayOptionsMenu();
		else if(_currentPage = Page.MoreGames)
			DisplayMoreGamesMenu();
		else if(_currentPage = Page.GameGuide)
			DispayGameGuideMenu();
		else if(_currentPage = Page.Addons)
			DisplayAddonsMenu();
		else if(_currentPage = Page.GameCenter)
			DisplayGameCenterMenu();
		else
			DisplayMainMenu();
	}

	public void DisplayMainMenu() {
		GUI.BeginGroup(new Rect(0,60,500,300));
		if(GUI.Button(new Rect((Screen.width / 2) - 100, 60, 200, 25), "New Game"))		//Change the page to NewGame menu
			_currentPage = Page.NewGame;
		if(GUI.Button(new Rect((Screen.width / 2) - 100, 90, 200, 25), "Resume"))		//Change the page to Resume menu
			_currentPage = Page.Resume;
		if(GUI.Button(new Rect((Screen.width / 2) - 100, 120, 200, 25), "Load Game"))		//Change the page to LoadGame menu
			_currentPage = Page.LoadGame;
		if(GUI.Button(new Rect((Screen.width / 2) - 100, 150, 200, 25), "Options"))		//Change the page to Options menu
			_currentPage = Page.Options;

		if(GUI.Button(new Rect((Screen.width / 2) - 250, 75, addonsButton.width, addonsButton.height), addonsButton))
			_currentPage = Page.Addons;
		if(GUI.Button(new Rect((Screen.width / 2) - 250, 135, moreGamesButton.width, moreGamesButton.height), moreGamesButton))
			_currentPage = Page.MoreGames;
		if(GUI.Button(new Rect((Screen.width / 2) + 250, 75, gameGuideButton.width, gameGuideButton.height), gameGuideButton))
			_currentPage = Page.GameGuide;
		if(GUI.Button(new Rect((Screen.width / 2) + 250, 135, gameCenterButton.width, gameCenterButton.height), gameCenterButton))
			_currentPage = Page.GameGuide;

		GUI.Label(new Rect((Screen.width / 2) - (gameNameTexture.width / 2), 10 - (gameNameTexture.height / 2), gameNameTexture.width, gameNameTexture.height), gameNameTexture);
		GUI.EndGroup();
	}

	void Update() {
		Debug.Log(_currentPage);
	}

use = to change a value. Use == to check a condition, like in an if statement.

The error means you are trying to put something thats not a bool in to a bool. It may happen if you check a variable for true or false thats not a bool. If you are trying to check if it exists use ‘null’.

To be direct, change

 if(_currentPage = Page.MainMenu)
DisplayMainMenu();

to

 if(_currentPage == Page.MainMenu)
DisplayMainMenu();

and do the same for the rest of the if statements
