Needing to call the function twice

[Codein]

What this script is meant to do is:

Show the characters the player currently has, and if there's an empty character slot, display Empty Character.

The problem is, I have to update the NPC or call showGUI() twice for changes to be made. For example, if I create a character and go back to the this GUI, it doesn't update the information until I call showGUI again.

Another example: I have to click the "Delete" button twice to show the changes.

I'm not very good with explanations, so it might be a little hard to understand.

PHP Code:

function onActionServerside() {
  if (params[0] == "getStats") {
    for (i = 0; i < 3; i++) {
      temp.info = new TStaticVar();
      temp.info.loadvars("mud/characters/" @ params[1] @ "_" @ i);
      
      temp.(@ "character_" @ i) = temp.info.savevarstoarray(0);
    }
    
    findPlayer(params[1]).triggerclient("gui", name, "returnStats", temp.character_0, temp.character_1, temp.character_2);
  }
  
  elseif (params[0] == "delete") {
    ("-SystemCharacter").deleteChar(player.account, params[1]);
  }
}
