checkout_shipping.php not found

[nutstretch]

I have installed oscommerce and am coming to an understanding with it. The problem I am having is that if i go to checkout it should be taking me to checkout_shipping.php. I get Error 404.

 

I have altered both configuration files to show the shared certificate. my code is as follows

admin/includes/configure.php

  define('HTTP_SERVER', 'http://www.womens-accessories.co.uk'); // eg, http://localhost - should not be empty for productive servers
 define('HTTP_CATALOG_SERVER', 'http://www.womens-accessories.co.uk');
 define('HTTPS_CATALOG_SERVER', 'https://dragon.unitedhosting.co.uk/womens-accessories.co.uk');
 define('ENABLE_SSL_CATALOG', 'true'); // secure webserver for catalog module

 

includes/configure.php

 define('HTTP_SERVER', 'http://www.womens-accessories.co.uk'); // eg, http://localhost - should not be empty for productive servers
 define('HTTPS_SERVER', 'https://dragon.unitedhosting.co.uk/womens-accessories.co.uk'); // eg, https://localhost - should not be empty for productive servers
 define('ENABLE_SSL', true); // secure webserver for checkout procedure?

 

any help with this would be really appreciated as it is frustrating me now.

 

Thanks in anticipation.
