I did actually see that, it's not being set in the form anywhere. But the reason I mention the empty field is because I did manage to submit the form twice but deleting that empty field (although for some reason it's not letting me do that anymore) also just to add some interger in there I put as default the now() function in that rowstamp field. And get the below error message which is also one I've seen on this form.
The form cannot be submitted because it contains validation errors. Errors are marked with either a red asterisk (required fields) or a red, dashed border (invalid values). Field or group: frbny_bf_appdiscid Error: Only integers allowed
