Hi there, @miss.k.owen… when you created the Illustrator field, you gave it a field type, and when you added the multidropdown element to the page, you defined its choices style (static or dynamic) and its type of choices (assuming you chose dynamic for the choices style). In order for you to be able to add the list of items selected in the multidropdown to the Illustrator field, the field type of that field and the type of choices defined for the multidropdown need to match. If you share screenshots of theBook data type (specifically, the Illustrator field) and the Appearance tab of the editor for the multidropdown, I’m sure we will be able to see the mismatch.
Best…

Edit with a quick example: on the User data type, I have a categories list field that is tied to an option set.
The type of choices for a multidropdown that I am going to use to save items to the categories list field needs to be set to the same option set.
