Why Cant My Parts Ever Move?

So Im Trying To Make A Maze Generator And At First I've Been Trying To Generate A Grid But When I Try And Duplicate the X Axis And Move It It Doesnt Move And I Did As A Test To Teleport The Duplicated Parts To 0,0,0 And Thats Not Working Either So What Is Going On Heres The Script btw

BIG = {X = 100, Y = 100, Z = 5}
Chunks = 20
Ratio = BIG.X*BIG.Y
Size = 1
T = 0
function X() -- Generating The X Value
	for i = 1,(Chunks * 10) do
		local ChunkSplit = T*(Chunks)
		print(ChunkSplit)
		local Part = Instance.new("Part")
		Part.Position = Vector3.new(0 - ChunkSplit,BIG.Z,0)
		Part.Size = Vector3.new(Chunks,Size,Size)
		Part.Anchored = true
		Part.Name = T
		Part.Parent = game.Workspace
		if T == Chunks then
			local Model = Instance.new("Model")
			Model.Parent = game.Workspace
			Model.Name = "X"
			for i = 0,Chunks do
				game.Workspace:WaitForChild(i).Parent = Model
			end
			break
		end
		T = T + 1
	end
end
function Y() -- Generating Duplicate X Blocks
	T = 0
	local XC = game.Workspace.X:GetChildren()
	local X = game.Workspace.X
	print(XC)
	for i = 1,#XC do -- Duplicates Blocks
		T = T + 1
		local Clone = X:Clone()
		local CloneC = X:Clone():GetChildren()
		Clone.Parent = game.Workspace
		print(CloneC)
		local ChunkSplit = T * Chunks
		for i = 1,#CloneC do -- Moves Indivual Blocks
			print(CloneC[i])
			CloneC[i].Position = Vector3.new(0,0,0)
		end
	end
end
X()
Y()

so uh I don't know what's wrong can anybody tell me what's happening or give me the fixed code please?

At line 36, you did not set CloneC's parent. The parent was turned to nil, therefore there is no reason to error when you put a part parent to nil. Consider set CloneC parent to workspace
