Ok this is a two part question:

1. I have an additional field that I created for when customers register. Can I add that field? And if so, how do I do it?

2. When I manually add a customer, it gives me the pretty green box that says "customer has been inserted successfully" but above that I have a red box that says "Warning: Invalid argument supplied for foreach() in /home/actforms/public_html/cart/admin/add_customers.php on line 71". I'm wondering if that has something to do with the additional field. If not, any ideas?

BTW, Thanks for the MOD, it's a big help!!
