Custom PlayerList script will not change Gui name or text?

I'm trying to make a custom Player List and need help. I have already disabled the default one and it doesn't show up, as planned. Here is my script. I will explain more down below.

game.Players.PlayerAdded:connect(function(Plr)
    wait(2)
    if script.Parent:FindFirstChild("Player") ~= nil then
        local Player = script.Parent.Player
        Player.Name = "InGame"
        Player.Text = " ".. Plr.Name
    end
end)

First off, the local Player is a the Text Label Gui that will display the player name. I am naming it "InGame" so the script doesn't find the same Player Gui that someone else is using. Help would be greatly appreciated. Oh forgot to mention; nothing shows up in the Output or Script Analysis.
