here is attached the step2.php page. Please keep in mind that in step1.php I set a session variable (numart_sess) that holds the number of copies I need to create about the fields Articolo and Barcode in step2. This is decided by the user in step 1 by using a dropdown menu (values range from 1 to 15 maximum).
So, basically, in step 2 I need to get maximum 15 Articolo fields and maximum 15 Barcode fields.
Then I need to validate all fields and save all fields values to session variables. In step3.php page I will display all collected data and save it to database (in a single record).
Thanks again, Ray.
