Who can fix this script? Plate not Disappear!

--Thanks to Sleazel for the Structure

Fixed.

Remove this line ->

local TogglePlate = Instance.new("BindableEvent")
TogglePlate.Name = "TogglePlate"
TogglePlate.Parent = ServerStorage

And change with this ->

local TogglePlate = ServerStorage:WaitForChild("TogglePlate")
