Perhaps I am reading this wrong, but it appears you are calling
mysql_query() using a variable called $sql which never has a value (thus
executing no query at all), and then in the next line of code you are
setting $query equal to your query.
Try doing $rs = mysql_query ($query, $conn); after you assign the string to
$query.
