Hi Russ,

It's not clear that you're keeping track of which categories are being checked.

You name them category[$names]  but you refer to them as $category[$i] where $i is a 
number.  How will you know what $category[1] refers to?

Other issues: It's also not clear where the value of $email comes from.  Nor is it 
clear if you're trying to obtain one row in the database with all subscriptions or 
you could have multiple lines for multiple subscriptions.

Try this

while (list($key,$val)= each ($HTTP_POST_VARS[category]) ) {

    $thisname=$key;  // this is the "name" of the checkbox, as in $category[$name]
    $thisval=$val;   // this is the value, which in every case is "yes"

    $sql="INSERT INTO $myanet02($thisname) values ($email)";
    // this will produce a line in the db for each subscription

    // if you want one line for all subscriptions, remvoe the $sql line above and
    // uncomment these lines below
    // to compound the sql and run the query after the while

    // if ($thefields) $thefields .= ", $thisname"; } else { $thefields = "$thisname"; 
    // if($thevalues) $thevalues .= ",'$email' " } else { $thevalues = "'$email'"; }

    $query = mysql_query($sql,$connect) or die(mysql_error());

} // end while

// uncomment following lines for single row entry
// $sql= INSERT INTO $myanet02($thefields) values ($thevalues)";
// echo $sql;
// $query = mysql_query($sql,$connect) or die(mysql_error());

kind regards,
