By default, each zone must be assigned to a different database field in FormPro. This is also true for checkmark zones that are evaluated to 0 or 1 by default. For multiple-choice questions or other groups of mutually exclusive answers, however, you often don’t need a separate database field for each checkbox but a common field into which the value of the checked answer should be written.
For checkmark zones, FormPro exceptionally allows to assign multiple zones to the same database field. The so grouped checkmark zones will be underlaid with a light gray frame and will appear as a zone group in the Batch Explorer. In the Zone Properties dialog, you can enter a different value for each zone of the group that is to be used as the value of the database field when this zone is recognised as being checked.
