help with openexternalpm()

[Angel_Light]

ok, so I'm just working with some stuff and I try to get a pm window open when a player just double clicks another, here's what I got:

PHP Code:

//#CLIENTSIDE

//...script...

function onMouseDown()
{

  if ( params[ 0] == "double")
  {

    this.pID = getPlayerID( mousex, mousey);
    
    if ( this.pID != -1 && this.pID != player.id)
    {

        players[ this.pID].openexternalpm( false);

    }
  }
}

function getPlayerID( temp.mx, temp.my)
{

  for ( temp.p = 0; p < allplayerscount; p ++)
  {
  
    if ( mx in | players[ p].x, players[ p].x + 2|  &&
         my in | players[ p].y, players[ p].y + 3|)
      return players[ p].id;

  }
  
  return -1;
} 


From what I can tell it should work, but when I double click nothing happens at all. What am I doing wrong?
