Plugin Help What went wrong?

Code:

@EventHandler
    public void PickRightClickSell(PlayerInteractEvent e)
    {
        Player p = e.getPlayer();
        if(p.hasPermission("lightningcustom.sella"))
        {
        if(e.getPlayer().getItemInHand().getType() == (Material.DIAMOND_PICKAXE))
       {
    if(e.getAction() == Action.RIGHT_CLICK_AIR || e.getAction() == Action.RIGHT_CLICK_BLOCK)
       {
        Player p1 = e.getPlayer();
        ItemStack i = p1.getItemInHand();
        ItemMeta im = i.getItemMeta();
        if (im.getDisplayName().equalsIgnoreCase("§c§lA-Pickaxe"))
        {
            Bukkit.dispatchCommand(p1, "sellall a");
        }
       }
    }
        }
        else
        {
           ItemStack item = p.getItemInHand();
           Action action = e.getAction();
           if (!(e.getAction() == Action.RIGHT_CLICK_AIR || action.equals(Action.RIGHT_CLICK_BLOCK))) return;
           if (!(e.getItem().getType() == Material.DIAMOND_PICKAXE)) return;
              p.playSound(p.getLocation(), Sound.LEVEL_UP, 1, 1);
              p.addPotionEffect(new PotionEffect(PotionEffectType.FAST_DIGGING, 20000000, 1));
              p.addPotionEffect(new PotionEffect(PotionEffectType.SPEED, 20000000, 1));
              p.getPlayer().setAllowFlight(true);
              p.getPlayer().setFlying(true);
        }
    }

So I made an Event Handler so it checks if you have permission then checks for a certain item name and dispatches the command "sellall a". I don't know what went wrong here there is an error obviously. Here is the event handler.

 

Please post in code BB code rather than plain text

 

well I don't know if that worked but code BB doesn't seem like its working for me... I pressed the button and even deleted it and repasted it in.

 

Put CODE in "[" and "]" before the code and /CODE in brackets after the code.

 

did it Thanks, now hopefully you can help with the problem.

 

Is there an error? What's the problem?

 

When I Right click the pickaxe with the correct permission [OP] it gives me a stack trace in the console:

Again, put it in BB code, but on line 71 there is a variable or method that is/returns null.
