Ok, changed the INSERT code to:
PHP Code:
$sql = "INSERT INTO customer SET
title='$title',
firstname='$firstname',
lastname='$lastname',
username='$username',
password='$password',
suburb='$suburb',
city='$city',
phonenumber='$phonenumber',
dob='$dob'";
$result = mysql_query($sql);
Which resulting in getting the message "Thank you! Information entered."
So checked my database and its added a new row with autonumber id 2 (second record in database) but the rest of the feilds are blank.
