Genereer meerdere checkboxes

Ik probeer hier om een tabel te maken, met daarin checkboxes, die allemaal de naam "C(id)" moeten hebben. ID is de ID van de member. Deze code heb ik nu, maar het werkt niet.

<?
print "<form method="POST" action="memberlist2.php"><br>";
include('connect.inc.php');
$query = mysql_query("SELECT * FROM members");

print "<table><tr bgcolor=#dcdcdc><td><font face=verdana size=1> # </td><td><font face=verdana size=1> Username </td><td><font face=verdana size=1> Ip </td><td><font face=verdana size=1> ? </td></tr>";
while ($gegeven = mysql_fetch_object($query)) {
$id = $gegeven->id;
$naam = $gegeven->username;
$ip = $gegeven->ip;

print "<tr><td><font face=verdana size=1>$id</td><td>";
print "<font face=verdana size=1>" . $naam . "</font><td>";
print "<font face=verdana size=1>$ip</td><td>";
print "<input type="checkbox" name="C" . $id ."" value="ON">";
echo"</td></tr> ";
}

print "</table><br><p><input type="submit" value="Delete" name="Submit"></p></form>";
?>
