Protecting PHP file outside of WP directory

I have a PHP/MySQL database app in the directory public_html/jobbase outside of WP which is in the directory public_html/wordpress.

I am embedding the main PHP page of the app into a WP page using an iframe. The WP page is protected via S2M. Now I need to protect the PHP page from being accessible outside of S2M.

Following the directions found at http://www.s2member.com/kb/protecting-non-wordpress-content-with-s2member/ I have inserted the following code at the top of my PHP page:

When I try to load the page when logged in as admin or a test user with Level 1 privileges, I get the “Permission denied!” response.

Does something need to replace “// User is allowed to view, so display something here.” to make this function and protect the external (from WP) PHP file?

TIA
