Can I use this Gun Globalizer with a class gui?

When using YouTubes old script (http://pastebin.com/3QpH1yhq) It only seems to work in starter pack. So, I tried changing the Tool.Parent section like so

    Tool.Parent = game.StarterGui.Classes.Frame.Class
end)
.....
Tool.Equipped:connect(function(Mouse)
    Equipped = true
    if Settings.Weld and not Welded then
        wait()
        Tool.Parent =game.StarterGui.Classes.Frame.Class
    end
    Character = Player.Character
    if Gui then

But that still doesn't properly address the guns. Meaning the player just floats with no weapon in hand. Is there anything I can do with this?
