Thanks, I did indeed select the top level post binding group.
The page is still not displaying the show region server behavior on the web page.
I think the php code should call up the other file in the security_assist folder: helpergroupsrulesphp.php. I think it is part of the php code below, or is it a separate line? Anyway, the helpergroupsrulesphp.php file isn't being referenced.
<?php require_once( "webassist/security_assist/helper_php.php" ); ?>
