How am I suppose to set the CFrame of a block higher than the last block CFame?

hello, scripters.

I'm trying to make a temporary ore spawn system that spawns ores in a vertical way however this is the first time i've tried and i'm confident this: local newcframe = primarypartcframe * CFrame.new(1,currentWidth+1,1) should work.. what am I doing this wrong?

	for i = currentWidth,maxWidth,1 do
		--// roll odds
		local block = chancemodule:Roll(chancetable.Tier1Layer)
				
		--// clone block
		local cloneblock = game.ReplicatedStorage.Ores[block]:Clone()
		cloneblock.Parent = workspace
				
		--// set block cframe
		local primarypartcframe = cloneblock:GetPrimaryPartCFrame()
		local newcframe = primarypartcframe * CFrame.new(1,currentWidth+1,1) --should work?
		cloneblock:GetPrimaryPartCFrame(newcframe)
				
		--// print currentWidth
		wait()
		print("currentwidth = "..i)
	end

hopefully this is enough info to help however if you need more info then i'll give it. :)
