Multiple Column Sorting Not Working

I cannot get multiple columns to sort. I can get only one, but when I add multiple, the page continues to come up blank.

a blank page means that a php error is occurring but error reporting is turned off.

to turn error reporting on, add the following code at line 1:

<?php
error_reporting(E_ALL);
ini_set('display_errors','on');
?>

once we know what the error is, we will be able to troubleshoot the cause.

You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'article_title' at line 1

the default sort setting needed to be updated to:
$WADA_Sort_1->DefaultSort = "ORDER BY article_title";

it is now showing an error about undefined variables:
Notice: Undefined variable: static_articles in D:\PLESK\VHOSTS\redsneakers.net\office-furniture\admin\article_list_test.php on line 217 Warning: mysql_fetch_assoc() expects parameter 1 to be resource, null given in D:\PLESK\VHOSTS\redsneakers.net\office-furniture\admin\article_list_test.php on line 217


this code:
<?php } while ($row_static_articles = mysql_fetch_assoc($static_articles)); ?>
is referencing a recordset that does not exist.

Thanks so much!

you're welcome.
