Thank you very much
all it is ok I add
define('FILENAME_SPECIALS', 'specials.php');
define('FILENAME_CATEDISCOUNT', 'catediscount.php');
define('FILENAME_CATEMANUDISCOUNT', 'catemanudiscount.php');
define('FILENAME_MANUDISCOUNT', 'manudiscount.php');
define('FILENAME_GROUPS', 'customers_groups.php');
and it works
The only problem is, that when I go to catalog/specials then I receive a completely blank page.
thnx again
