I tried a code that can show up a gui by hovering over with the mouse but nothing shown?

local Player = Game.Players.LocalPlayer
local Mouse = Player:GetMouse()

Mouse.Move:connect(function()
    if Mouse.Target and Mouse.Target == Workspace.SpecialHoverBrick then
Player.PlayerGui.ScreenGui.SpecialHoverGui.Visible = true
    elseif Mouse.Target and Mouse.Target ~= Workspace.SpecialHoverBrick then
        Player.PlayerGui.ScreenGui.SpecialHoverGui.Visible = false
 end
end)
