Script Working Offline, Inaffective Online

[Gambet]

What? I've always done..

NPC Code:

---

//#CLIENTSIDE

function onMouseDown()

{

 if ( params[0] == "left" ) {

  player.chat = "You have just left clicked!";

 } else if ( params[0] == "right" ) {

  player.chat = "You have just right clicked!";

 } else if ( params[0] == "double" ) {

  player.chat = "You have just double clicked!";

 } else if ( params[0] == "middle" ) {

  player.chat = "You have just clicked on your mouse wheel!";

 }

}

..and it's always worked fine for me.
