neilo is correct, the problem is in the code for checking if the username already exists:


// *** Redirect if username exists
if (isset(
$_POST[$MM_flag])) {
$loginUsername $_POST['EmailAddress'];
$LoginRS__query "SELECT EmailAddress FROM user WHERE EmailAddress='" $loginUsername "'";
$LoginRS=mysql_query($LoginRS__query$Roseshuttle) or die(mysql_error());
$loginFoundUser mysql_num_rows($LoginRS);

The redirect:

ends up pointing to:

but the failed.php page exists at:

The redirect needs to be changed to:

The cause of the failure is a different matter. In the Users table, you have a record where the user name is blank.

Additionally, you changed the name of the UserName form element from "EmailAddress" to "UserName".

When a user attempts to register, the duplicate username code is using the original name for the userName form element to look for duplicates:
$loginUsername = $_POST['EmailAddress'];

since this for element no longer exists, the value it is looking for is blank ("")

$loginUsername = $_POST['EmailAddress'];

$loginUsername = $_POST['UserName'];

so it will use the correct form element when looking for duplicate usernames:<td width="160"><input class="WAATKTextField" name="UserName" id="UserName" value="" size="25" type="text"></td>
