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
