public class TokenShop implements Listener {
    public static  Drugs plugin;
    public TokenShop(Drugs instance){
        plugin = instance;
    }
 
 
    //TOKEN SHOP
    public static Inventory tokenshop = Bukkit.createInventory(null, 27, ChatColor.RED+""+ChatColor.BOLD+"Token Shop");
 
    static{

        }
    @EventHandler
    public void onInventoryClick(InventoryClickEvent event) {
    Player player = (Player) event.getWhoClicked(); // The player that clicked the item
    ItemStack clicked = event.getCurrentItem(); // The item that was clicked
    Inventory inventory = event.getInventory(); // The inventory that was clicked in
    int PlMoney = plugin.getConfig().getInt(player.getName()+".Money");
 
    if(clicked.getType() == Material.NETHER_STAR && clicked.getItemMeta().getDisplayName().equals(ChatColor.BOLD+"Token Shop")){
        event.setCancelled(true);
    }
 
    if (inventory.getName().equals(tokenshop.getName())) { // The inventory is our custom Inventory
 
        if (clicked.getType() == Material.SEEDS && clicked.getItemMeta().getDisplayName().equals(ChatColor.RED+"African Kush"+ChatColor.GREEN+" "+ChatColor.BOLD+Integer.toString(plugin.getConfig().getInt("AfghanKush"))+"GEMS")){ // The item that the player clicked it dirt
 
 
            event.setCancelled(true); // Make it so the dirt is back in its original spot
     
            if(plugin.getConfig().getInt(player.getName()+".Money") < plugin.getConfig().getInt("AfricanKush")){
     
                player.sendMessage(ChatColor.RED+"Im sorry but you don't have enough money to buy that!");
     
            }else{
             
                PlMoney = PlMoney - 1000;
             
                player.sendMessage(ChatColor.RED+"YOUR NEW BALANCE IS "+ String.valueOf(PlMoney) + " GEMS");
 
                player.closeInventory();    // Closes there inventory
 
                player.getInventory().addItem(new ItemStack(Drugs.setName(new ItemStack(Material.SEEDS), ChatColor.RED+"African Kush")));
 
            }
 
        }
 
        // Adds Item
     
 
 
    }
 
 
    }

              p.openInventory(tokenshop);
            p.playEffect(p.getLocation(), Effect.BLAZE_SHOOT, 4);
            plugin.playFirework(event.getPlayer().getLocation(), Color.AQUA);
       
        }

So as far you can read from the code im trying to make a inventory menu , when i interact with the TOKEN SHOP item it opens the inventory ( which is not and i don't know why ) and i am trying to sell a item named AfricanKush (Named AfganKush in config) but it won't do nothing...it won't even open the inventory,..any help? Thanks!
