Hi I am trying to keep information that is input via a form. This form may be used 1, 2, 3, 4 or more times for each entry. Meaning that the form will be filled out and added then another of the same form filled our and so on until the person clicks the the complete button. Can I hold this info by session or do I have to insert it into the database after each time? I would rather not put it into the database until the session is complete and they have a chance to verify their entry. Thanks Kevin
