My door script isn't working, and this title isn't letting me say that alone?

I made a script where my door is supposed to change position and rotation when it is clicked. It's not working and I don't know why. I kept looking for little details but nothing works. Here is my attempt at the script.

part = script.Parent
position = Vector3.new(0.65, 3.675, -26.85)
rotation = Vector3.new(0, 60, 0)
mainposition = Vector3.new(-0.45, 3.675, -28.45)
mainrotation = Vector3.new(0, 0, 0)

script.Parent.ClickDetector.MouseClick:connect(function(playerWhoClicked)
	if (part.Position == position and part.Orientation == rotation) then
		part.Position = part.Position.mainposition
		part.Orientation = part.Orientation.mainrotation
		part.CanCollide = true
	elseif (part.Position == mainposition and part.Orientation == mainrotation) then
		part.Position = part.Position.position
		part.Orientation = part.Orientation.rotation
		part.CanCollide = false
	else
		print("Door script failed.")
	end
end)
