First time using a ModuleScript. How do I stop this error?

ModuleScript:

function OpenDoor(LO, RO, LC, RC, FLOOR)
	print("YAY")
	local TweenService = game:GetService("TweenService")
	local TweenINFO = TweenInfo.new(1,Enum.EasingStyle.Linear,Enum.EasingDirection.Out,0,false,0)
	local OpenLeft = {CFrame = CFrame.new(LO)*CFrame.Angles(0,math.pi/2,0)}
	local OpenRight = {CFrame = CFrame.new(RO)*CFrame.Angles(0,math.pi/2,0)}
	local ClosedRight = {CFrame = CFrame.new(LC)*CFrame.Angles(0,math.pi/2,0)}
	local ClosedLeft = {CFrame = CFrame.new(RC)*CFrame.Angles(0,math.pi/2,0)}
	if workspace.ElevatorRoom.OnFloor.Value ~= FLOOR then
		repeat wait() until workspace.ElevatorRoom.OnFloor.Value == FLOOR 
	elseif workspace.ElevatorRoom.OnFloor.Value == FLOOR and script.Parent.Open.Value == false then
		local openleft = TweenService:Create(script.Parent.Parent.ElevatorFrame.Left, TweenINFO, OpenLeft)
		local openright = TweenService:Create(script.Parent.Parent.ElevatorFrame.Right, TweenINFO, OpenRight)
		script.Parent.Open.Value = true
		openleft:Play()
		openright:Play()
		for i = 5, 1, -1 do
			print(i)
			wait(1)
		end
		local closeleft = TweenService:Create(script.Parent.Parent.ElevatorFrame.Left, TweenINFO, ClosedRight)
		local closeright = TweenService:Create(script.Parent.Parent.ElevatorFrame.Right, TweenINFO, ClosedLeft)
		closeleft:Play()
		closeright:Play()
		script.Parent.Open.Value = false
	end
	print("Ended")
end

return OpenDoor()

script:

local OpenDoor = require(workspace.ModuleScript)
script.Parent.ClickDetector.MouseClick:Connect(function()
	OpenDoor(
		13.7, 4.4, 35.351,
		13.7, 4.4, 48.451,
		13.7, 4.4, 44.35,
		13.7, 4.4, 39.45,
		1		
		)
end)

errors: 16:51:20.097 - Workspace.ModuleScript:6: bad argument #1 to 'new' (Vector3 expected, got nil) 16:51:20.110 - Requested module experienced an error while loading

any help is greatly appreciated
