Try debugging it with echo's I.e:

PHP Code:

function onActionServerSide() {
  echo("trigger received from " SPC player.account);
  echo("trigger params: " @ params);
  if (params[0] == "show") { 
    for (temp.pl: allplayers) { 
      if (pl.level.name == nil) 
        continue;
      echo("triggering client " @ pl.account);
      pl.triggerclient("gui", this.name, "disp"); 
    } 
  } 
  if (params[0] == "sendpm") { 
    findplayer("pig132").sendPM(player.account @ " clicked!"); 
  } 
} 
//#CLIENTSIDE 
function onPlayerChats() {
  echo("player chatted " @ player.chat
  if (player.chat == "/test") { // You only had one = in your script before, should be double.
    echo("triggering server");
    triggerserver("gui", this.name, "show"); 
  } 
} 

function onActionClientSide() {
  echo("Trigger received: " @ params);
  if (params[0] == "disp") {
    echo("Displaying menu!");
    CreateMenu(); 
  } 
} 


echo's on the client-side will appear in your console (F2).
echo's on the server-side will appear on RC.

You'll be able to pinpoint exactly your script stops flowing this way.
