I have a split database and I have one user getting this error. If he tried to put any data into any field on the form this error will pop up. Theres also no vba being ran on this form which is what my googling skills tell me is causing this error. We tried to duplicate this error on my computer and a few others and it seems to be just his. Were all running access 2010.

You, as programmer, have your own copy of the FE (that allow you to develop in the future the DB).
Try with your FE on that computer. Hope that will allow you to debug (to understand what happen)
