A form processing method edits at least one target field in a form. The form processing method determines the type of the form, determines whether an editing instruction is given to edit the target field interdependently with a related field relating to the target field, if the type of the form is a predetermined type of form, and edits the target field interdependently with the related field, if it is determined that the editing instruction is given to edit the target field interdependently with the related field.
