Coffe machine works in studio but not in live? there is no error

i made a coffee machine that uses transparency stuff and tool manipulation; the screen is a surfaceGui in a part called "Screen" which has a normal script (not localscript)

but the problem is that when pressing done, it will not make any coffee

function Click()
local username = game.Players.LocalPlayer.Name
local char = game.Workspace:FindFirstChild(username)
if script.Parent.Parent.Parent.Parent.FoamEnabled.Value == true then
script.Parent.Parent.Parent.Parent.Spill4.Transparency = 0
end

script.Parent.MouseButton1Down:connect(Click)

this is the model https://www.roblox.com/catalog/976000342/redirect

by the way, the mug comes from ServerStorage. it comes with the model, so you have to move the tool to ServerStorage.
