I am building a dynamic site for the company I work for , to enable managers throughout the company to order stock on-line which will register at a central database.

I am new to web design of any kind, but so far have managed to design my site install a test server and link to my database (access 2000). The question is can I perform on-line calculations as the orders are being placed or do I have to install "shopping cart"?

Thanks in advance
