FYI, and for what it's worth, the code was all in place, but a simple typo was made in creating the modules/pages/band_signup/header_php.php file. ... instead of header_php.php, it was mistakenly loaded up as header.php.php.

I share this simply for the benefit of others who might have some troubles when creating custom pages for their site ... filename accuracy is important ;)

Nice site Wayne... all the best in your upcoming launch!
