Why is my door saying that position is not part of the model?

Im new to lua coding and I wanted to make a door that works on click so I looked up a tutorial and copied it exactly. 2 hours later I'm sure I have everything the same and his works. the error message i am getting is "position is not part of the model. here is my code

local model = script.Parent.Parent.Parent
local door = model.door 
local value = script.Opened.Value
local close = model.Close
local open = model.Open

script.parent.MouseClick:Connect(function(player)
	if value == false then
		value = true
		door.Position = open.Position
		door.orientation = open.orientation
	elseif value == true then
			 value = false
		door.position = close.position
		door.orientation = close.orientation
			end
end)
