Code:
on *:JOIN: {
  if ((%Join) || ($($+(%,Join.,$nick),2))) { return }
  set -u25100 %Join. $+ $nick
  .timer 1 2 msg $chan Welcome to the stream $nick have a great time! c: Kreygasm new viewer.
}

I need help with this code, I want it to welcome people on twitch and have it happen once every day. Help would be greatly appreciated.
