trying to make a invatory script and i ran into a problem at the for loop part?

ok so here is my code

game.Players.PlayerAdded:Connect(function(p)
	
	slots = Instance.new('Folder', p)
	slots.Name = 'slots'
	
	slot1 = Instance.new('Folder', slots)
	slot1.Name = 'slot1'
	
	slot2 = Instance.new('Folder', slots)
	slot2.Name = 'slot2'
	
	slot3 = Instance.new('Folder', slots)
	slot3.Name = 'slot3'
	
	slot4 = Instance.new('Folder', slots)
	slot4.Name = 'slot4'
	
	weapons = Instance.new('Folder', p)
	weapons.Name = 'weapons'
	
	a = game.ReplicatedStorage.tool:Clone()
	a.Parent = weapons
	
	b = game.ReplicatedStorage.tool:Clone()
	b.Parent = weapons
	
	for i,o in ipairs(p.weapons:GetChildren()) do
		for v,b in ipairs(p.slots:GetChildren()) do 
			if b:FindFirstChild('tool') == nil then
				print('it broke!')
				break
			else
				o.Parent = b
			end
			
		end
	end
	
	

so what this is (Suppose) to do is make a weapons folder, a slots folder and inside the slots folder 4 other folders and then the game will grab weapons from the replicated storage andn put it in the weapons folder then this is were im lost im trying to get all of the weapons inside the weapons folder and put it in a slot individually if that makes since so if a slot has a weapons inside of it ('tool') then it would move on to the next slot and put it there can somone please guide me on how to do this?
