Help with parse error

[windows]

Here's the link - <!-- m --><a class="postlink" href="http://www.karinne.net/admin/">http://www.karinne.net/admin/</a><!-- m -->

Here's the error - Parse error: parse error, unexpected T_STRING in /home/karinne/karinne.net/admin/index.php on line 21

Here's the code -

$conn = pg_connect ("dbname=karinne user=karinne password=karinne");

$auth = false; // Assume user is not authenticated

if (isset($PHP_AUTH_USER) && isset($PHP_AUTH_PW)) {

$login = pg_exec ("select * from users where userid='$PHP_AUTH_USER' and password='$PHP_AUTH_PW'");
$num = pg_numrows($login);

if ($num != 0) {
$auth = true;
}
}

if (!$auth) {
header( 'WWW-Authenticate: Basic realm="Private"' )
header( 'HTTP/1.0 401 Unauthorized' );
echo 'Authorization Required.';
exit;
} else {
header( 'Location: /jeep/' );
}


What's bold is line 21... I've never used the $PHP_AUTH_USER and _PW before so I'm kinda lost!?!

TIAI was missing a ; on line 20! DOH!!
