this should work
Thanks for the suggestion but that didn't work I'm afraid. I have the trigger set to the form submit button being pressed. This uploads a new file and enters the file name in the database but if pressed without uploading a new file, it does not retain the info in the database (it deletes it). All this despite following the guide for this very thing found here http://assets.webassist.com/how-tos/dfp_da_insert_update_ht.pdf
