Cheer system through mIRC

Unfortunately, No succes.

<- @badges=subscriber/1,bits/100;bits=1;color=#0000FF;display-name=ImDippinIn;emotes=;id=799fcaf5-d134-44fb-9d3f-6068f70bfb23;mod=0;room-id=31640426;subscriber=1;turbo=0;user-id=67889083;user-type= :imdippinin!imdippinin@imdippinin.tmi.twitch.tv PRIVMSG #aethos19d :cheer1

And the code in mIRC is:

on $*:text:/(^|\s)cheer\d+(\s|$)/i:#: {
  if (($msgtags(room-id).key == 31640426) && ($msgtags(bits).key)) {
    if ($2- == $null) {
      describe $chan $msgtags(display-name).key donated $msgtags(bits).key Bits SeemsGood
    }
    else {
      describe $chan $msgtags(display-name).key donated $msgtags(bits).key Bits SeemsGood with the message " $2- " MVGame
    }
  }
}
