event is a nil value?

wait(1)
local event = nil;
local name = nil;

event.OnServerEvent:Connect(function()
	for _,plr in pairs(game.Players:GetPlayers()) do
		delay(1, function()
			print("Running Sources")
		event = plr:WaitForChild("PlayerGui").CoreGui.KickPlayer:WaitForChild("Remote Kick")
		repeat
			 wait()
		until
			event
		name = event.Parent:WaitForChild("PlayerName")
	print("a")
	if game:FindFirstChild(name.Text) then
		print("b")
		game.Players[name.Text].Character:Remove()
		print("c")
		wait()
		print("d")
		game.Players[name.Text].PlayerGui.CoreLoadingGui.Error.Visible = true
		print("e")
		game.Players[name.Text].PlayerGui.CoreLoadingGui.Error.ErrorText.Text = "[ CLIENT DISCONNECTED ]: You have been kicked from this game."
		print("f")
			end
		end)
	end
end)
