I was trying to make a Gui pop up on the screen when I hover over, but it wont show up?

local Player = Game.Players.LocalPlayer
local Mouse = Player:GetMouse()
03
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)
