follow up to Mora's msg
I have the same problem and would like to know if you were able to solve the database problem.
My db settings/trigger is identical to yours and yet it is not working, not collecting any data and don't know what to do anymore, everything works perfectly except db.
By inserting the trigger it has caused another problem as well, the customer information is not passed thru anymore to Authorize Net, the $/tax/shipping all is passed on to authorize net but not the info entered by the customer.
So now I'm dealing with 2 new problems and feeling totally lost.
