Hi all, I'm looking to create a table where I can pass alterations to an SQL statement. Say I have a form returned to me and at the top of each column is a button with the column name. If I click on a button, the SQL statement gets altered and the results are reverse-sorted. This is what I have so far: 
use strict;

my ($order_by,$sql,$asc_desc);

$sql = qq{SELECT * FROM TABLE}; 

$order_by = param('order_by');
$asc_desc = param('asc_desc');

if (defined($order_by)) {
  if ($asc_desc eq 'ASC') {
    $sql .= " ORDER BY $order_by ASC ";
  } 
  else {
    $sql .= " ORDER BY $order_by DESC ";
  }
}

print header,
  
  start_html(),
  start_form(),
  
  center(
     p($order_by),
     start_table(),
     Tr(td(submit('order_by','FAULT_NO',)),
        td(submit('order_by','ISSUE')),
        td(submit('order_by','RESPONSE'))),
     end_table(),
     hidden('order_by',$order_by),
     hidden('asc_desc',$asc_desc),
     p($sql),
    ),
  
  end_form(),
  end_html();

exit;

Don't worry about column name generation for now... Now the default SQL is 'SELECT * FROM TABLE' and when I press the 'FAULT_NO' button, the SQL statement becomes 'SELECT * FROM TABLE ORDER BY FAULT_NO DESC'. Similar results for the other buttons. Looks like I have the table column changing as it should, but I'm having a bugger of a time trying to get the 'ORDER BY' bit to change from DESC (take as default) to ASC... A little help please? Many thanks, Stacy.
