Help with making this place block script work correctly?

I am trying to make this script place a block, but when I hit the correct button, nothing happens (Yes selected has a value, game.Lighting.1) Here is the script:

--LocalScript
local player = game.Players.LocalPlayer
local Mouse = player:GetMouse()
local Placing = false
local Already = false
function Place()
	local Xpos = Mouse.Target.Position.X
	local Ypos = Mouse.Target.Position.Y
	local Zpos = Mouse.Target.Position.Z
	local Surface = Mouse.TargetSurface
	local TargetPos = Mouse.Target.Position
	local Selected = game.Players.LocalPlayer.Selected.Value
	local Clone = Selected:Clone()
	Clone.Position = Vector3.new(TargetPos)
	if Surface == 1 then
		Clone.Position = Vector3.new(Xpos, Ypos + 4, Zpos)
	else
		if Surface == 4 then
			Clone.Position = Vector3.new(Xpos, Ypos - 4, Zpos)
		else
			if Surface == 3 then
				Clone.Position = Vector3.new(Xpos - 4, Ypos,  Zpos)
			else 
				if Surface == 0 then
					Clone.Position = Vector3.new(Xpos + 4, Ypos, Zpos)
				else
					if Surface == 2 then
						Clone.Position = Vector3.new(Xpos, Ypos, ZPos + 4)
						if Surface == 5 then
							Clone.Position = Vector3.new(Xpos, Ypos, Zpos - 4)
						else
							print(" ")
						end
					end
				end
			end
		end
	end
end

Mouse.Button2Down:connect(function()
	local Find = Mouse.Target:FindFirstChild("Xplo")
	if not Already then
	Already = true
	Placing = true
	if Find then
	while true do
		wait(1)
		if Placing == true then
			Place()
		else
			print(" ")
		end
	end
	end
	end
	end)

Mouse.Button2Up:connect(function()
	Already = false
	Placing = false
end)
