Follow-up question to "How would I change the LookVector properties for this door script"?

So the previous question that I asked worked, but for some reason, the door doesn't fully go up, and I don't know what to change to make it go farther. Here's the code if you need it:

for i = 0.1,(door.Size.z / 0.014) do
		door.CFrame = door.CFrame - (door.CFrame.UpVector * 0.014)
		wait()
	end
