hi i have installed it but it messes up at the finally stage
the site is http://noisestopsystems.com/buy_soundproofing/
pluss i dont know how to do the first bit
1.) SQL statements needed just copy and paste these into your SQL query window and hit 'Go':
ALTER TABLE `orders` ADD `cvvnumber` VARCHAR(4) default NULL AFTER `cc_expires`;
***If you have not altered your Configuration Table in the database:
INSERT INTO configuration VALUES ( 185, 'CVV2 Number', 'CVVNUMBER_MIN_LENGTH', 3, 'Minimum Length of CVV2 Number', 2, 17, '2004-01-08 10:30:00', '2004-01-08 10:30:00', NULL , NULL );
***If you have made some alterations to the Configuration Table you will need to change the '185' and '17' to represent the next configuration_id and sort_order(group 2) for your particular database.
INSERT INTO configuration VALUES ( 186, 'CVV Max Length', 'CVVNUMBER_MAX_LENGTH', 4, 'Maximum Length of CVV Number', 3, 19, '2004-01-08 10:31:00', '2004-01-08 10:31:00', NULL , NULL );
***As in the previous entry the '186' and '19' might be different if you have already modified your configuration table. The '4' is the value for maximum length of the CVV number which is needed for American Express cards (the 3 in the query is the group_id so don't change). If you just plan on accepting Visa/MC/Discover you can change this to '3' in the query or the number can also be changed in your admin tool->configuration->maximum values
2.) Either replace your files with the complete files provided or do the modifications included with each filename.txt
3.) Upload new file popup_cvv.php
4.) Upload all image files found throughout both directories.
can anyone help?
