How come this stats script is not working properly?

So, the script has to grab the stats and show it up on a gui for some reason the script is not working.

local GUI = script.Welcome
local stats = script.playerstats

join = (function (Player)
	local GuiClone = GUI:Clone()
	if not Player.Character then 
		Player.CharacterAdded:wait()
	end
	local statsClone = stats:Clone()
	statsClone.Parent = Player
	GuiClone.Frame.Visible = false
	GuiClone.Parent = Player:findFirstChild("PlayerGui")
end)

game.Players.PlayerAdded:connect(join)
for _,v in next, game.Players:GetPlayers() do
	join(v)
end
