why my inventory item sorting script isnt working?

im not rly good at scripting and im trying to make a basic inventory. so here is my script which is supposed to sort items (put them into the inventory gui)

local plrname = game.Workspace:WaitForChild("PlayerName") -- a string value with players name inside
local plr = game.Players:WaitForChild(plrname.Value) -- player
local inv = plr:WaitForChild("Inventory") -- custom folder
inv.ChildAdded:Connect(function()
	local items = inv:GetChildren()
	local itemsnumber = #inv:GetChildren()
	if itemsnumber > 0 then
		local item = items[1]
		item.Parent = script.Parent.Items
		for i,v in pairs(script.Parent.Items:GetChildren()) do
			if v.Claimed ~= nil then
				if v.Claimed.Value == false then
					v.Claimed = true
					empty = v
					return
				end
			end
		end
		item.Position = empty.Position
	end
end)

not sure but i think it doesnt work because of the return. so what i want to do is when the for i loop finds an empty slot it stops and runs the second part after the loop. any help will be appreciated
