I have a form letter template builder where the user can create a letter and insert placeholders to be substituted with FileMaker field data. (e.g. <<FirstName>> = Contacts::FirstName) Pretty standard stuff. I would like to add a placeholder that indicates the record ID of a related record that would then be substituted in place of the placeholder. (e.g. <<MyField1245>> = MyTable::MyField Record #1245)
How might I do this?
