Need Help Please

Hello. I wanna make editable message in config.
How can i make this?

Code:

            Player p = (Player) sender;
            if(!staff.contains(p.getName())){
                staff.add(p.getName());
                p.sendMessage(ChatColor.GOLD + "Staffchat toggled " + ChatColor.AQUA + ChatColor.BOLD + "ON");
                return true;
            }else if (staff.contains(p.getName())){
                staff.remove(p.getName());
                p.sendMessage(ChatColor.GOLD + "Staffchat toggled " + ChatColor.DARK_RED + ChatColor.BOLD + "OFF");
                return true;
            }
            }
          
            return true;
        }

 

Nope. Isn't work (I tried already)

What does not work? Can you post the code you used? Are you sure the path is correct?

 

also make sure you save the config with saveConfig() after you edit it
