Where is the local script located?

[RecanValor (recanman)]

Since you are referring to the StarterGui, which is not the PlayerGui, it is not going to do anything. Here is the correct code:

local codeOpenbutton = script.Parent
local player = game.Players.LocalPlayer
local Code = player.PlayerGui.ScreenGui.Codes

codeOpenbutton.MouseButton1Up:Connect(function()

    Code.Visible = true

    Code:TweenSizeAndPosition{
        UDim2.new(0.471, 0, 0.284, 0),
        UDim2.new(0.277, 0, 0.991, 0),
        "Out",
        "Quad",
        .5,
        false
    }
end)

Just replace this:

@recanman

{

For this:

Oh yes, thanks for that. I just had to rewrite the code and messed up there.
