How can I update a select menu using multiple update ?

Hi there, I'm trying to do a multiple update with a select menu EXAMPLE

<select name="select" id="select">
<?php
while(!$Lang_RS->atEnd()) { //dyn select
?>
<option value="<?php echo($Lang_RS->getColumnVal("lang_id")); ?>"<?php if (!(strcmp($Lang_RS->getColumnVal("lang_id"), ($DefaultLang_RS->getColumnVal("name"))))) {echo "selected=\"selected\"";} ?>><?php echo($Lang_RS->getColumnVal("name")); ?></option>
<?php
$Lang_RS->moveNext();
} //dyn select
$Lang_RS->moveFirst();
?>
</select



but multiple update records look up for repeated form


like this

<?php
$wa_startindex = 0;
while(!$Lang_RS->atEnd()) {
$wa_startindex = $Lang_RS->Index;
?>


<?php
$Lang_RS->moveNext();
}
$Lang_RS->moveFirst(); //return RS to first record
unset($wa_startindex);
unset($wa_repeatcount);
?>
And select menu does not work with this selection.
So what is the way to do this ?
