How can i make something like a book with pages?

I am making a tutorial for my game, and I ran into one problem. I want to make it so that you can press a button that says "Next" but I just cannot figure out how to do this. Here is my code so far. Any help would be greatly appreciated.

script.Parent.MouseButton1Click:Connect(function()
	local page = 1
	if page == 2 then
		page = page + 1
		print(page)
	end
	if page == 1 then
		page = page + 1
	end
	if page == 3 then
		script.Parent.Parent.TextLabel.Text = "Cool! Now you are at one of the most important places in the game, the C++ Hub!  The C++ hub is where you can learn things about C++, and you can also test your knowledge!"
		page = page + 1
	end
	if page == 2 then
		script.Parent.Parent.TextLabel.Text = "Ok. follow the arrows that lead to the TV near the 'learn' sign. "
		print(page)
		page = page + 1
	end
end)
