1. Check the last Batch entry for blank fields (e.g. Gift Type, Fund). Make sure all required fields have entries.
2. If all fields are populated, delete the last gift row and re-enter the gift.
3. If still unresolved, create a new batch from scratch (do not load from existing template). If error no longer occurs set up the same as the old batch, use the new one as the batch template moving forward and delete the old one.
