This code keeps giving an error when I perform the command, I've fixed a few variable mistakes but that still doesn't fix it.
Can anyone help me out? It's a null pointer, but I don't see anything that gives a null. Thanks!

Here are the itemstacks
static ItemStack hasMoney = new ItemStack(Material.YELLOW_FLOWER, 1);
static ItemStack helm=new ItemStack(Material.LEATHER_HELMET, 1);
static ItemStack nextHelm=new ItemStack(Material.GOLD_HELMET, 1);
After reading that you can find the line an error went wrong, i tracked down it was to do with vault. Later on i worked out i haven't hooked a eco plugin like essentials! Anyway, thanks for the help, now if i have a problem,i know how i can troubleshoot myself.
