on *:text:!set *:#:{

  elseif ($2 == gratz) && ($3 == on) && ($address($nick,4) == $address($me,4)) {
    set %grats on 
    msg # [Grats is now Activated] 
  }
  if (%grats == off) {
    msg # [Grats is already Desactivated] 
  }
  elseif ($2 == gratz) && ($3 == off) && ($address($nick,4) == $address($me,4)) {
    set %grats off

}

Other things work well
