Code:
raw USERNOTICE:*:{
 if (resub isin $msgtags) {
    msg $1 Thank you $msgtags(display-name).key for subbing $msgtags(msg-param-months).key months in a row! $str(Kappa $chr(32),$msgtags(msg-param-months).key)
  }
}

This hasn't been tested. However the main thing that you want is the $str(Kappa $chr(32),$msgtags(msg-param-months).key) which will multiply the message based on the number of months they subbed for.
