Why are my cframes messed up?[closed]

I have tried changing these values up, down, making them the same as each other. Nothing has seemed to work. I am making a door that opens when clicked. It opens just fine but each time I close it, it moves just slightly left and forward. Again I have tried the CFrame Values exactly the same going up the least possible increment going down the least possible increment. Still the same result. This is the code I wrote.

local door = false
local NoGlitchy = false --debounce
script.Parent.ClickDetector.MouseClick:connect(function()
	if NoGlitchy == false then 
		NoGlitchy = true
	if door == false then	
		for i = 1,16 do
			wait()
			script.Parent.CFrame = script.Parent.CFrame * CFrame.new(0,-.18,0.009) * CFrame.fromEulerAnglesXYZ(-0.098,0,0)	
		end
		door = true
		wait(0.3)
		NoGlitchy = false
	elseif door == true then
		for i = 1,16 do
			wait()
			script.Parent.CFrame = script.Parent.CFrame * CFrame.new(0,.178,0.007) * CFrame.fromEulerAnglesXYZ(0.098,0,0)	
		end
		door = false
		wait(0.3)
		NoGlitchy = false	
	end
	end
end)

If anyone could help I would be very happy.

I found a rather simple solution to my problem.

local cframe = script.Parent.CFrame -- I simply needed to add this
local door = false
local NoGlitchy = false --debounce
script.Parent.ClickDetector.MouseClick:connect(function()
	if NoGlitchy == false then 
		NoGlitchy = true
	if door == false then	
		for i = 1,16 do
			wait()
			script.Parent.CFrame = script.Parent.CFrame * CFrame.new(0,-.18,0.009) * CFrame.fromEulerAnglesXYZ(-0.098,0,0)	
		end
		door = true
		wait(0.3)
		NoGlitchy = false
	elseif door == true then
		for i = 1,16 do
			wait()
			script.Parent.CFrame = script.Parent.CFrame * CFrame.new(0,.179,0.007) * CFrame.fromEulerAnglesXYZ(0.098,0,0)	
		end
		script.Parent.CFrame = cframe -- and this
		door = false
		wait(0.3)
		NoGlitchy = false	
	end
	end
end)

Now it works perfectly.
