I am wondering if a list can be returned in alpha order (ascending) based on two fields within the database rather than only one when someone clicks on the "list all" link?

<form action="$db_script_url" method="GET" name="form1">
<input type=hidden name="db" value="$db_setup">
<input type=hidden name="uid" value="$db_uid">
<input type="hidden" name="sb" value="LastName"> <-- can this use two fields rather only one?
<input type="hidden" name="so" value="asc">
<input type="hidden" name="ww" value="1">
