how do fix my gui because its not tweening?

local ShopGui = game.StarterGui.ShopUI.ShopGui


script.Parent.MouseButton1Click:connect(function()
ShopGui:TweenPosition(UDim2.new(0.15,0,0.0023,0), 'Out', 'Sine', .7)
end)

I've tried countless times modifying this but it doesn't seem to work

A few things I need to know.

• Is this a local script? If Filtering Enabled is set to true the click function would not be connected.
• On top of this, you are manipulating the gui in the actual StarterGui rather then the local players PlayerGui.

Try

local Player = game:GetService('Players').LocalPlayer
local UIService = Player:WaitForChild('PlayerGui')

local ShopGui = UIService.ShopUI.ShopGui


script.Parent.MouseButton1Click:connect(function()
ShopGui:TweenPosition(UDim2.new(0.15,0,0.0023,0), 'Out', 'Sine', .7)
end)

:: Run this from a Local Script.
