Using a lookup between parent and child projects

Hello! I’ve deployed parent and child projects (one is a registration form, and the other will be to follow-up on an intervention). Is it possible to make a lookup field for participant (name: full_name on the parent project) on the follow-up form so that you can type in the participant name and the list displays those with that name?

(You can see I tried select_one_from_file but I makes sense that wouldn’t work since the participant name is in a separate csv file but a “Dynamic Data Attachment”.)

Parent project:

Child project:

Thank you!

@lzlzlz, did you mean you wish to see the (list of) all the names that match (in the parent form) when typing the name when filling out the child form?

Feel free to correct me if I understood your issue differently.

Yes, exactly :slight_smile: Any help is appreciated!
