function open()
local DoorWhole = script.Parent.Parent.Parent.Parent
DoorWhole.DoorOpened.Handle1.Transparency = 0
DoorWhole.DoorOpened.Handle2.Transparency = 0
DoorWhole.DoorOpened.Part.Transparency = 0
DoorWhole.DoorOpened.Handle1.CanCollide = true
DoorWhole.DoorOpened.Handle2.CanCollide = true
DoorWhole.DoorOpened.Part.CanCollide = true
end
script.Parent.MouseClick:connect(open)
^ That's the script.

Is there any error? Is this a Script or a LocalScript?
This is a regular script, no errors appear in Output.
What isn't working exactly?
The entire thing. The door doesn't show up and I can walk through where it should go.
Have you enabled "FilteringEnabled"?
Is the script inside the clickdetector?
