Data Persistence Load GUI?

I'm working on an virtual phone, and I'm looking to save Apps, but the only thing stopping me from doing that is this script, it won't work...can someone please help me?

game.Players.PlayerRemoving:connect(function(p)
p.CharacterAdded:wait()

 MainPhone = p.PlayerGui["RoOS Phone"]["Screen"]["Windows"].FindFirstChild("Phone")
    if MainPhone then
        p:SaveInstance("Phone_datastore", p.Character)
    end
end)

game.Players.PlayerAdded:connect(function(p)

 MainPhone = p.PlayerGui["RoOS Phone"]["Screen"]["Windows"]["Phone"];
p.CharacterAdded:wait()
datafolder = p:LoadInstance("Phone_datastore");
apps = datafolder["App Files"];
Home = datafolder["Screen"]["explorer.exe"]["Homescreen"]["homeScreen"];

    MainPhone["App Files"]:Remove();
    MainPhone["Screen"]["explorer.exe"]["Homescreen"]["homeScreen"]:Remove();

    apps.Parent = MainPhone;
    Home.Parent = MainPhone["Screen"]["explorer.exe"]["Homescreen"]["homeScreen"];

end)
