MailMergeFields.AddFillIn (Word)

Adds a FILLIN field to a mail merge main document. Returns a MailMergeField object.

When updated, a FILLIN field displays a dialog box that prompts you for text to insert into the document at the location of the FILLIN field. Use the Add method with the Fields collection object to add a FILLIN field to a document other than a mail merge main document.
