How can I create a database for BV Sign-up forms

[hs3443]

Hi
I have create a website, with a protected members page.
To redirect my members into this page I have included a sign up form, created by BV. But I cannot create a database for this.
I make a userdb.php file, but it doesn't works

Is there anybody who can tell me how to make it workable.

Thanks a lot
