trying to make a bot to detect if a user that is banned is coming onto channel with a new nick under the banned one while on a new IP....

when it do:
Code:
on *:NOTICE:*Information on*(account*:?: {
  if ($nick == nickserv) {
    msg #testingchannel $5
  }
}


it comes back with:

$5 = ORIGINALNICK):

how can i make it get rid of the "):" so it can check properly?
