well we would need to know what the database is !!
assuming MySQL with a connection like ..
mysql_connect('localhost',$user,$pass)or die(mysql_error());
mysql_select_db($database)or die(mysql_error());
then I assume the loop would look something like this
<option value="none">none </option>
<?
$res=mysql_query(" SELECT member FROM member ");
while($row=mysql_fetch_row($res)){
?>
<option value="<?=$row[0];?>"><?=$row[0];?></option>
<?}?>
though what <%=form%> is I dunno 🙂
