Anvil Canceling not working

I am trying to cancel the anvil for specific items it works but the player can click rapidly with any item(one that I'm canceling or not) and it will give me a ton of errors(with what I am trying to do still working) heres my code

Code:java

 
    @EventHandler
    public void NoAnvil(InventoryClickEvent event) {
    if (event.getInventory().getType() == InventoryType.ANVIL && event.getSlotType() == SlotType.CRAFTING) {
    ItemMeta im = event.getCursor().getItemMeta();
    if(im.hasLore())
    if(im.getLore().contains(ChatColor.DARK_AQUA + "Freebuild Item"))
    event.setCancelled(true);
    }
    }

 

What are the errors?

 

chasechocolate Oops forgot here

Code:

Edit: line 59 in the hasLore part I have no idea why it's giving me an error there

 

monkeymanboy check if event.getCursor().hasItemMeta() before creating the ItemMeta variable.

 

chasechocolate It works now except now if the player puts it in say their 9 slot then click 9 it moves the item there then they can make the item any way around that?
