[SOLVED] Vault integration help!

Hi!

Here is a piece of my code:

Code:

public boolean onCommand(CommandSender sender, Command cmd, String commandLabel, String[] args){
        Player player = (Player) sender;
        double price = Config.getDouble("price");
        EconomyResponse r = econ.withdrawPlayer(player.getName(), price);
        if(commandLabel.equalsIgnoreCase("buyheal") || commandLabel.equalsIgnoreCase("bh")){
            if(player.hasPermission("buyheal.heal")){
                econ.withdrawPlayer(player.getName(), price);
            if(args.length == 0 && r.transactionSuccess()){
                player.setHealth(20);
                player.sendMessage(ChatColor.GOLD + "You healed yourself for " + r.amount + " " + econ.currencyNamePlural());
            }else{
                player.sendMessage(ChatColor.DARK_BLUE + "You" + ChatColor.RED + " don't " + ChatColor.DARK_BLUE + "have enough money");
            }
            }
        }else{
            player.sendMessage(ChatColor.RED + "You can't do that, bro!");
        }
        return false;
    }

It doesn't have an error message but, when i run command /buyheal it says a long error message on the console:

Code:

        ... 15 more

P.S.:It's still working if i change to econ.withdrawPlayer(player.getName(), 20); and if i delete double price = Config.getDouble("price"); but i want to pay the price which is configured by the user.

Solved, sorry for that.
