Well it would be good to get the numbers back because it would tell you which fields it thinks are failing.
After line 5 add this:
<?php @session_start(); ?>
Then on your page somewhere you can see it add this:
<?php
echo("failed: " .ValidatedField('registration','registration'));
?>
Let me know the results. If you still have issues, attach just the registration.php page in your reply so I can take a look.
