Need Main Page Text on Product Pages

Ok I've played with some code and still having trouble trying to get this to work. What I need is the main page text (from the define pages editor) to show on the product info pages. I really need this to work somehow. I've tried inserting the similar code after the bread crumbs with no luck. Any ideas?

Try adding it to a copy of /includes/templates/template_default/templates/tpl_product_info_display.php placed into your templates override structure

Yes I did I'm just struggling with the syntax as it seems when I insert it the product pages do not load. I tried to insert the following before the product class and it still gets an error but not sure what I'm doing wrong. I even placed the define statement in and even tried renaming $define_page to match thinking it was duplicating in some way but still doesn't work. It's probably a syntax error of some type... Any ideas?

$define_page = zen_get_file_directory(DIR_WS_LANGUAGES . $_SESSION['language'] . '/html_includes/', FILENAME_DEFINE_MAIN_PAGE, 'false');

/**
 * get the Define Main Page Text
 */
<div id="indexDefaultMainContentProduct" class="content"><?php require($define_page); ?></div>
<?php } ?>

Well I figured it out by using the "include" function as opposed to "require" just for troubleshooting. The header does not load the variable "$define_page" for the product pages and I could not define it in the same class. I know I'm stumbling through PHP here but I did accomplish what I needed. The define main page text is now at the top of my product pages. Maybe someone else can benefit from it too? Let me know if I can help as this will allow me to place text for sales, coupons, etc... directly in the pages as when I get hits from the shopping sites they land directly on the product pages not the main page.
