I'm trying to make a spawn script, but it only spawns one time, why?

The script is here; It only spawns one item, and doesn't spawn any more.

local itemName = script.Parent.itemName
local user = game.Players.LocalPlayer
local plrName = script.Parent.getName


script.Parent.spawnItem.MouseButton1Down:connect(function()
	local item = game.Lighting.Items:FindFirstChild(itemName.Text)
	if item ~= nil then
		item:clone()
		
	local plr = game.Players:FindFirstChild(plrName.Text)
	local backpack = plr.Backpack
	
		item.Parent = backpack
end; end)
