PHP Scripting question?

[DIVAD3]

I am questioning this part of things as well. Because I don't understand why I have nothing stated as far as a email would be concerned if I am having the values and password indicating something. The actual Register php page has a place for an entry of a email.
http://www.detailzusedcars.com/us-au...4/register.php and this page also indicated a failure to connect to database as the login page does.

This is from the register.php:

// Fields are clear, add user to database
// Setup query
$q = "INSERT INTO `dbUsers` (`username`,`password`,`email`) "
."VALUES ('".$_POST["admblogdetailzus"]."', "
."PASSWORD('".$_POST["OLIVIAlynn616"]."'), "
."'".$_POST["email"]."')";
// Run query
$r = mysql_query($q);
