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)
