This script does not open up a gui when I step on a brick. It is t he right brick and the right GUI. No errors, no nothing, just doesn't work.
local part = game.Workspace.Model.Part1
local shopgui = game.Players.LocalPlayer.Shop1Gui.Frame
part.Touched:connect(function(part)
shopgui.Visible = true
end)
Turns out turning FilteringEnabled off and then on again fixed it.

Any output and is the game filtering enabled?
