            Player player = (Player) sender;

                String item = player.getInventory().getItemInHand().getData().toString();
                if (item == null) {
                    player.sendMessage(ChatColor.RED + "You are not holding anything!");
                    return false;

                if(price==0){
                    player.sendMessage(ChatColor.RED + "No sell data has been set. Please ask an admin for a price.");
                    return false;
                }
               
                //player.sendMessage("Holding "+item);//line for testing
                player.sendMessage(ChatColor.GREEN + "For 1 " + item
                        + " the price should be "+price);

            } else {
                System.out.print(ChatColor.RED
                        + "This can only be done from in game.");
