Code:
raw 319:*: {
  echo 1: $1  2: $2  3: $3  4-: $4-
; This will show you the value of each string.
  set %usrtotnumopdchns %match($3,@,0,32) ; change $3 accordingly
  set %usrtotnumopdchns.org %usrtotnumopdchns
  while (%usrtotnumopdchns) {
    set %useropedchan %match($2,@,%usertotalopedchans,32)
    set %totaluseropedchans $addtok(%totaluseropedchans,%useropedchan,32)
    dec %usrtotnumopdchns
  }
  echo -s Channels $nick is op'd on %usrtotnumopdchns.org : %totaluseropedchans
  %unset %totaluseropedchans
}

I registered; you should too.
