Could someone tell me what I did wrong in making this GUI for my game?

Player = game.Players.LocalPlayer
Menu = script.Parent
Play = Menu.About
About = Menu.About
HasPressedPlay = false
Info = script.Parent.Info
Minimize = Info.Minimize
function MouseEnterPlayButton()
	Play.FontSize ="Size36"
	Play.BackgroundColor3 = Color3.new(0.35, 1, 1)
	Play.Size = UDim2.new(0.45, 0, 0.225, 0)
end
function MouseLeftPlayButton()
	--85, 255, 255
	About.FontSize ="Size24"
	About.BackgroundColor3 = Color3.new(0.1, 0.647, 0.7)
	About.Size = UDim2.new(0.45, 0, 0.225, 0)
	end

function MouseEnterAboutButton()
	Play.FontSize ="Size36"
	Play.BackgroundColor3 = Color3.new(0.35, 1, 1)
	Play.Size = UDim2.new(0.45, 0, 0.225, 0)
end

function MouseLeftAboutButton()
	About.FontSize ="Size24"
	About.BackgroundColor3 = Color3.new(0.54, 0.62, 0.7)
	About.Size = UDim2.new(0.3, 0, 0.15, 0)
	end

function PlayGame()
    if HasPressedPlay == false then 
        for GuiMove = 1, 30 do
		if 	GuiMove <= 20 then
            	Play.Position = Play.Position +UDim2.new(0.05, 0, 0, 0)
        	end
            if GuiMove >= 10 then
				About.Position = About.Position +UDim2.new(0.05, 0, 0, 0)
			end
			wait()
        end
    	Menu:remove()
    end
end


function MinimizeInfo()
	Info.Visible = false
end

function InfoPopup()
	if Info.Visible == false then
	Info.Visible = true
	else
		Intro.Visible = false
end

About.MouseButtonDown:connect(InfoPopup)
Minimize.MouseButton1Down:connect(MinimizeInfo)
About.MouseLeave:connect(MouseLeftAboutButton)
About.MouseEnter:connect(MouseEnterAboutButton)
Play.MouseLeave:connect(MouseLeftPlayButton)
Play.MouseLeave:connect(MouseEnterPlayButton)
Play.MouseButton1Down:connect(PlayGame)

Line 52: You should always add an end for every 'if' statement. Other than that I see no error. Of course, I could be wrong.

function InfoPopup()
    if Info.Visible == false then
    Info.Visible = true
    else
        Intro.Visible = false
end
end
