Zen Cart 1.3.8a
PHP Version 5.2.5

I recently downloaded and set up my cart. It can be viewed at survivethedrive.info/cart.

I'm selling online training vouchers. I not sure how to set the product up so it will pull a voucher number that can be used in our online training section. These vouchers are sequential and stored in a database.

This is all very new to me. Any help would be appreciated.
