Try this...

Code:
 
on *:TEXT:*:?:{
  if ($active != $window($nick)) {
    if ($me isin $1-) {
      splay $mircdirsounds\misc\dingding.wav 
      echo -at $nick has mentioned your nick in private
    }
  }
}
on *:ACTION:*:?:{
  if ($active != $window($nick)) {
    if ($me isin $1-) {
      splay $mircdirsounds\misc\dingding.wav 
      echo -at $nick has mentioned your nick in private
    }
  }
}

Scripto ---- Life is about the relationships. The correct code being: $replace($them,$you,$me)
