How do you store a CFrame value in a table?

I'm experimenting with CFrame and tried storing a CFrame value to a table. I had struggles with it. How do you do it?

Here's my code and please answer with details. My code is some kind of detection. I think detection of which if a part went out of a certain area it will turn red, otherwise green.

BrickMode = true -- Just some kind of mode to find it using parts. I need to make invisible points without depending on bricks. Just CFrame points.









model = nil
axis = 1
neg = 0
if BrickMode == true then
	if workspace:FindFirstChild('SurfaceDetectionPoints') then
	model = workspace.SurfaceDetectionPoints
	else
		Instance.new("Model",workspace).Name = 'SurfaceDetectionPoints'
		model = workspace.SurfaceDetectionPoints
	end
	for o = 1,6 do
		newIns = Instance.new("Part",model)
		newIns.Color = Color3.new(0,1,0)
		newIns.Anchored = true
		newIns.Size = Vector3.new(0.2,0.2,0.2)
		newIns.Material = "Neon"
		newIns.CanCollide = false
		newIns.Name = "SURFACEDETECTIONPART"
	end
end
-- Creates an instance for keeping the parts
while true do
	
	size = script.Parent.Size
	points = {
		script.Parent.Size.Z / 2,
		script.Parent.Size.Z / 2,
		script.Parent.Size.X / 2,
		script.Parent.Size.X / 2,
		script.Parent.Size.Y / 2,
		script.Parent.Size.Y / 2
	}
	-- Above are points for simple surface detection.
	
	
	if BrickMode == true then
		newPart = model:GetChildren()
	end
	for i = 1,#points do
		invisPoints = {}
		-- setting
		cAxis = nil
		if axis == 1 then
			if neg == 0 then
				cAxis = Vector3.new(0,0,points[i])
			else
				cAxis = Vector3.new(0,0,-points[i])
			end
		elseif axis == 2 then
			if neg == 0 then
				cAxis = Vector3.new(points[i],0,0)
			else
				cAxis = Vector3.new(-points[i],0,0)
			end
		elseif axis == 3 then
			if neg == 0 then
				cAxis = Vector3.new(0,points[i],0)
			else
				cAxis = Vector3.new(0,-points[i],0)
			end
			
		end
		
		-- start
		
		if BrickMode == true then
			newPart[i].CFrame = CFrame.new(script.Parent.Position)
			*CFrame.fromOrientation(math.rad(script.Parent.Orientation.X),math.rad(script.Parent.Orientation.Y),math.rad(script.Parent.Orientation.Z))
			*CFrame.new(cAxis)
		end
		table.insert(invisPoints,nil,{CFrame.new(script.Parent.Position)
			*CFrame.fromOrientation(math.rad(script.Parent.Orientation.X),math.rad(script.Parent.Orientation.Y),math.rad(script.Parent.Orientation.Z))
			*CFrame.new(cAxis)}) -- Where it went down. <<<<<<<<<<<<<<<<<<<
		-- presetting
		if neg == 1 then
			if axis == 1 then
			axis = 2
			elseif axis == 2 then
				axis = 3
			elseif axis == 3 then
				axis = 1
			end
		end
		if neg == 0 then
			neg = 1
		else
			neg = 0
		end
	end
	calcWidth = {left = workspace.Inside.Position.X + (workspace.Inside.Size.X/2), right = workspace.Inside.Position.X - (workspace.Inside.Size.X/2)}
	calcHeight = {up = workspace.Inside.Position.Y + (workspace.Inside.Size.Y/2), down = workspace.Inside.Position.Y - (workspace.Inside.Size.Y/2)}

		detect = workspace:FindPartsInRegion3(region)
		for _,Part in pairs(detect) do
			if Part.Name == 'SURFACEDETECTIONPART' then
				pass = pass + 1
			end
		end
		if pass == 6 then

			end

Thanks in advance.

Good night.
