I couldn't see this in your earlier mail but does the error occur inside a PHP function? I would assume so and this could be due to not seeing the previously defined variables because they are not declared as being in the global scope. Do you have code like this in your routine handling the form output? [CODE] function form_handling () { global $filter, $filterfield; // the rest of the HTML form output <form action="index.php" method="post"> <table class="bd" border="0" cellspacing="1" cellpadding="4"> <tr> <td><b></b>   ; </td> <td><input type="text" name="filter" value="<?php echo $filter ?>"></td> <td><input type="submit" name="action" value="Search"></td> ... } [/CODE] Regards and keep us posted, Sascha -- PHP Windows Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
