I tried that, but I reordered the dependants to try and figure out which one and the number indicating which line the dependant causing the error did not change.  It would help if ProSeries provided more information.  I was preparing a return for a non-custodial parent who it was their turn to claim 3 children.  The software stated only one was causing the error but we couldn't figure out which one or if some combination of the 3.  The custodial parent apparently claimed 1, 2, or 3 of the children.  It was VERY frustrating.
