osCommerce Guru required for small upgrade

There are 3 parts to this osCommerce project: Part 1 ===== I need to implement a security code entry field in the customer order process (these are the 3 digits found on the reverse of the customers credit card) which writes this to the database along with the rest of the credit card and order details and displays the output for the shop owner in the /admin area od oscommerce for order processing. Here are the files I think need updates (or at least the main ones from what i can see): [login to view URL] ------------------------------- Needs a field for customer to complete called: corresponding to field "cc_ccc" in the ORDERS table of the database This file should also show a (What's this?) link to a pop-up window for the user to explain the 3 digits on the back of the card. This file will be named ccc_pop_up.html. You are not required to create this explanation file for the user. We have one here:) [login to view URL] ------------------------------------- Needs to show cc security code entered by customer. admin/[login to view URL] ------------------------- Additionally, i need to show 3 digit cc security code at the backend in: See the screenshots attached showing what i require. 1. [login to view URL] 2. [login to view URL] Part 2 ===== I would like you to install the SEO friendly URL's contribution to the site also. Part 3 ===== When the user views products in any category I would like to have these ordered by price from lowest to highest (price ascending) from top to bottom of page. I will issue you with phpMyAdmin access to check the orders table in the database (I've added an extra field "cc_ccc" for the 3 digits already. I will issue an FTP Login to upload and test the new files live on the server. Let me know when the changes are ready to test pls:) If you have any questions please contact me. Many Thanks Doug
