Underlig fejl med mysql_fetch_array

Hej

Jeg har en underlig fejl på denne kode:

<?php
include "http://localhost/~gunnar/scripts/connect_db.php";

$row = mysql_fetch_array(mysql_query("SELECT * FROM ts_text WHERE id = $_GET[id]"));

$head = $row['head'];
$body = $row['body'];

echo $head;
echo $body;
?>


Det jeg "sender ind" er:

http://localhost/localhost/~gunnar/index.php?id=about (som henviser til siden text_show.php)


Fejlen er:

Warning: mysql_fetch_array(): supplied argument is not a valid MySQL result resource in /Users/gunnar/Sites/pages/text_show.php on line 4


Hvad går galt? Kan man ikke bruge tekst i sit id?


Mvh
Gunnar
