I have copied and pasted your demo code and Im getting this error after submission for registration here: http://wicknvape.com/create-login/

I really wanted to combine the form here: http://wicknvape.com/wholesale/ and have the registration info at the top, but that would not work either even though you said we could have additional fields.  Can you please help to at least get the registration form working?  There is no reference to a First Name in the registration form
