I did not mention that as user edits in form2, related records in other tables are changed and sometimes even other records in main table are affected because of crazy labor rules. For this reason I need to go back to the original question of how to do transactions within a transaction.

Thanks Naomi.

Would you suggest starting a new transaction as soon as entering form2 which is commited or rolled back according to user response?
