I need help linking my new pages to the sidebar items

ZEN 1.5
Custom Template

I've created a site at http://www.timberlinemeat.com/index.php and need help linking two items up, but can't seem to tell where in the coding the disconnect is happening?

Delivery & Storage and Links aren't showing up right, instead of it going to the correct page /index.php?main_page=delivery_storage to goes to /index.php?main_page=FILENAME_DELIVERY, the same happens for links it should go to /index.php?main_page=links not /index.php?main_page=FILENAME_LINKS

Any help? I've gone thorough multiple tutorials and tried to backtrack to find out where the coding is wrong, but I need help!

thanks in advance!!

Can't tell with your site down for maintenance.

Sorry..its back up now...Any help would be awesome! Thanks!

FILENAME_DELIVERY and FILENAME_LINKS don't exist in a stock Zencart installation, so they're define names that you've added somehow, and failed to define them in the process. How exactly did you add those links to the Information sidebox ?

I defined them in the includes/languages/english/english.php file like this?

// information box text in sideboxes/information.php

define('BOX_HEADING_INFORMATION', 'Information');

define('BOX_INFORMATION_DELIVERY', 'Delivery & Storage');

define('BOX_INFORMATION_LINKS', 'Links');

define('BOX_INFORMATION_SHIPPING', 'Shipping & Returns');

define('BOX_INFORMATION_CONTACT', 'Contact Us');

define('BOX_BBINDEX', 'Forum');

define('BOX_INFORMATION_UNSUBSCRIBE', 'Newsletter Unsubscribe');

Was that right?
