ON $*:TEXT:/(fuck|shit|whatever)/Si:#:{  
  if ($nick == $me) { | halt }
  if ($nick !isreg $chan) { | halt }
  else {
    inc %warning [ $+ [ $nick ] ]
    if (%warning [ $+ [ $nick ] ] <= 3) { /kick $chan $nick You've had %warning [ $+ [ $nick ] ] $+ warning's, don't do it again! $calc(3 - %warning [ $+ [ $nick ] ] ) left. }
    if (%warning [ $+ [ $nick ] ] >= 3) { /ban -ku600 $chan $nick You've had your warning's! You have now been banned for 10minutes. }
  } 
}

how can i get it to unset %warning [ $+ [ $nick ] ] after the last kick? otherwise it just bans them without kicking.
