[SOLVED] What's wrong with my script?

I am setting up an admin panel for my game. Everything in the script seems to be okay, but the output says the PlayerGui is not a member of Player...

What did I do wrong? How can I fix my mistakes?

Here's my code:

function Entered(Player)
	
	local isAdmin = {["Bolohuc"] = true, ["Bolohucalt"] = true, ["Bolohucalt2"] = true}
 
function findPlayer(name)
    for _, Player in ipairs(game.Players:GetPlayers()) do
        if Player.Name:lower() == name:lower() then
            return player
        end
    end
end
	
	if isAdmin[Player.Name] then Player.PlayerGui.Server.Tabs.Admin.Visible = true print(Player.Name .. "isAdmin") else print (Player.Name .. "isnotAdmin") end
	
end

game.Players.ChildAdded:connect(Entered)

I SOLVED THIS PROBLEM MYSELF. THANKS!

local Admins = {["bolohuc"] = true, ["bolohucalt"] = true, ["bolohucalt2"] = true} -- Declare this outside of the function for global usage
-- I'd enter them in lowercase to allow the script to compare a lowercase version to them

function Entered(Player) -- This function will be called every time a Player joins the game
	if Admins[Player.Name:lower()] then
	print(Player.Name .. " is admin")
	-- It may look a little sloppy, but I'd try it.
Player:WaitForChild("PlayerGui"):WaitForChild("Server"):WaitForChild("Tabs"):WaitForChild("Admin").Visible = true
	else
		print(Player.Name .. " is not an admin")
	end
end

game.Players.PlayerAdded:connect(Entered) -- I'd use PlayerAdded

Put the PlayerGui in StarterGui.
