Hello, thank you for taking the time to read this. Anyways.

I have everything correctly set up in workspace. Yet Im getting a error? Its probably a stupid little mistake on my part.

Links: http://prntscr.com/bra09p

My error:

Workspace.Script:40: bad argument #1 to '?' (CFrame expected, got nil) Script 'Workspace.Script', Line 40 Stack End

My code:

local mod = workspace.Model
local run = game:GetService("RunService")

local pos = {
	16,
	16,
	16
}

local old_rots = {
	['Left'] = workspace.Model.Left.Light.Movement.CFrame;
	['Right'] = workspace.Model.Right.Light.Movement.CFrame;
	['Middle'] = workspace.Model.Middle.Light.Movement.CFrame;
}

print(type(old_rots[1])) -- -> "nil"

local function clerp(p1,p2,percent)
    local p1x,p1y,p1z,p1R00,p1R01,p1R02,p1R10,p1R11,p1R12,p1R20,p1R21,p1R22=p1:components()
    local p2x,p2y,p2z,p2R00,p2R01,p2R02,p2R10,p2R11,p2R12,p2R20,p2R21,p2R22=p2:components()
    return CFrame.new(p1x+percent*(p2x-p1x),p1y+percent*(p2y-p1y),p1z+percent*(p2z-p1z),
        p1R00+percent*(p2R00-p1R00),p1R01+percent*(p2R01-p1R01),p1R02+percent*(p2R02-p1R02),
        p1R10+percent*(p2R10-p1R10),p1R11+percent*(p2R11-p1R11),p1R12+percent*(p2R12-p1R12),
        p1R20+percent*(p2R20-p1R20),p1R21+percent*(p2R21-p1R21),p1R22+percent*(p2R22-p1R22))
end

while wait(1) do
	local mod2 = mod:GetChildren()[math.random(1,#mod:GetChildren())]
	if mod2 then
		local light = mod2.Light
		if light then
			local movement = light.Movement
			if movement then
				local lightp = ((movement.Parent).LightPart)
				local old_rot = old_rots[movement.Name]
				local new_rot = pos[math.random(1,#pos)]
				for i = 1,50,1 do
					movement.CFrame = clerp(movement.CFrame,
						old_rot
						*CFrame.Angles(new_rot, 0, 0)
					,.1)
					lightp.CFrame = movement.CFrame*CFrame.new(0,1.2,0)
					run.Heartbeat:wait()
				end
			else
				print'3'
			end
		else
			print'2'
		end
	else
		print'1'
	end
end
