Why isn't my admin help system script working in Roblox?

Hello,

I'm currently making a Roblox game and want to add an admin help system to HD Admin. But the script isn't working, and I don't see any errors in the script:

 local adminUsernames = { "Mein Roblox username", "Admin2" } local function isPlayerAdmin(player) local playerName = player.Name:lower() for _, adminName in pairs(adminUsernames) do if playerName == adminName:lower() then return true end end return false end game:GetService("Players") .PlayerAdded:Connect(function(player) player.Chatted:Connect(function(message) if message:upper() == "!HELP" and isPlayerAdmin(player) then for _, adminName in pairs(adminUsernames) do local admin = game.Players:FindFirstChild(adminName) if admin then game:GetService("Chat"):Chat(admin.Character, player.Name .. " benötigt Hilfe!", "Red") end e nd end end) end)
