thanks for help.

I think this is the classical situation where you must add a field in some table ("products" if the extra field is related to a product), and then modify the "admin"section to input and modify the value, and the "store" section to show the value wherever you want.
Giovanni.

For that you need to create a new type of product and I tell you in advance, if you aren't a programmer, it won't be easy. For details go to your "Docs" folder of your ZC download and look for the "product_types_readme.html" file. There you will find the information to get started.

Have fun!
