Error^^

This is in a local script its only a bit of code, the bit that has to do with the door. its in player gui.

PLR.Character["Torso"].Touched:connect(function(hit)
if hit.Name == "DoorOpen" then
game.Players.LocalPlayer:GetMouse().KeyDown:connect(function(key)
if key == " " then
print'Opened Localscript'
if hit.Parent.DoorPart.Open.Value ~= true and hit.Parent.DoorPart.Closed.Value ~= false then
testModule.DoorOpen()
end
if key == " " then
print'Closed Localscript'
if hit.Parent.DoorPart.Closed.Value ~= true and hit.Parent.DoorPart.Open.Value ~= false then
testModule.DoorClose()
end
wait(5)
hit.Parent.DoorPart.Script.Disabled=true
elseif hit.Parent.DoorPart.Script.Running.Value == true then
return end
end
end)
end
end)
