i'm new in oscommerce and i want to install a module, i don't know if the version of oscommerce and the module is all right so, i gone to ask for get some help.
I need add one filed more in register called RFC and i find this http://addons.oscommerce.com/info/4816.
Well when i put in the database the query for the field MySql says: "Error : Duplicate entry '198' for key 1"
MySql code:
INSERT INTO configuration VALUES (198, 'RFC', 'ACCOUNT_RFC', 'true', 'Mostrar el campo para el RFC', 5, 1, NULL, '2007-20-01 11:41:12', NULL, 'tep_cfg_select_option(array(\'true\', \'false\'),');
ALTER TABLE address_book ADD entry_rfc varchar(16) NOT NULL default ''AFTER entry_company;
ALTER TABLE orders ADD billing_rfc VARCHAR( 16 ) AFTER billing_company ;
My version of oscommerce is v2.3
