in between the strong tags you have $use dont you mean $user

why dont you try

<? if(usernameTaken($_POST['user'])){
      $use = $_POST['user'];
}else{
		 echo"Sorry, the username: <strong>$user</strong> is already taken, please pick another one.";
}
?>

hmm the die you have should work. but try using an exit

<? if(usernameTaken($_POST['user'])){
      $use = $_POST['user'];
}else{
         echo"Sorry, the username: <strong>$user</strong> is already taken, please pick another one.";
exit();
}
?>

include("database.php");
include("login.php");

/**

 */
function usernameTaken($username){
   global $conn;
   if(!get_magic_quotes_gpc()){
      $username = addslashes($username);
   }
   $q = "select username from customer where username = '$username'";
   $result = mysql_query($q,$conn);
   return (mysql_numrows($result) > 0);
}

/**
 * Inserts the given (username, password) pair
 * into the database. Returns true on success,
 * false otherwise.
 */
function addNewUser($username, $password){
   global $conn;
   $q = "INSERT INTO customer (Firstname, Surname, Company, Email, Type, Tel, Mob, username, password) VALUES ('$_POST[first]', '$_POST[surn]', '$_POST[comp]', '$_POST[email]', '$_POST[type]', '$_POST[tel]', '$_POST[mob]', '$username', '$password')";
   return mysql_query($q,$conn);
}

/**
