Why is this trigger part not triggering?

I wanna make a soda fountain and when the player's cup touches the trigger part, it displays the soda in the cup and from the spout, but I wanna use a print statement just to make sure it works, and nothing comes up in the output. (This is inside a local script inside of the trigger part)

local tp  = script.Parent

local cup = game.Players.LocalPlayer.Backpack.Cup

tp.Touched:Connect(function(hit)
	if hit.Parent.Name == "Cup" then
		print("works")
	end
end)

Hello.

LocalScript's only run if it's a descendant of the following:

• ReplicatedFirst

• StarterPlayerScripts

• StarterCharacterScripts

• A player's character

• PlayerGui

You put the LocalScript inside a part that is inside Workspace. Instead, put it inside one of those.
