because the level name is a string and needs to be surround by quotes, otherwise it is read as variable. Also it is bad styling to have commands outside functions, so here what I would do.

PHP Code:

function onCreated()
{
  findPlayer( "Schetti").addweapon(this.name);
}

function onActionserverside()
{
  switch ( params[0])  
  {
    case "oslwarper":
      if ( findPlayer( params[ 1]).account != NULL) 
        setlevel2( "osl.nw", 27, 22);
      else
        findPlayer( params[ 1]).chat = "Account name" SPC findPlayer( params[ 1]).account SPC "not found!";
    break;
  }
}

//#CLIENTSIDE
function onPlayerChats() 
{
  if (player.chat == "Warpus Oslensis" && player.account != "Graal686747")  
    triggerserver("gui", this.name, "oslwarper", player.account);
} 


Hope this helps. =]
