echo '<option value="">Select ..</option>';
while ($row = mysql_fetch_arr ay($res))
{
$va1 = $row['untcode'];
if(isset($_POST['unt']) )
{
if($va1==$_POST['unt'])
{
echo "<option value='$va1' selected>$va1</option>";
}
else
{
echo "<option value='$va1'>$v a1</option>";

}
echo '</select>';
?>

Hi,

On the page where you have your combobox, is that all the code for that page? What does 'sel()' do?

I would recommend that if want to fill the values of the other combobox, use an AJAX script or POST the data into the same page.

Cheers
