Hi Matt,

Datasets typically do not have issues with lookups and dropdown boxes usually do generate.

However, what kind of datasets are you lookup to? Most datasets usually have 2-3 fields that are looked at for its primary key functionality, such as ParticipantId & Date, ParticipantId & VisitId, or the other two with a 3rd value being used. (Demographics datasets are an exception since it mainly uses the ParticipantId as its primary key.)

Do you have a sample study archive you could provide us that shows this dataset you created with all of its lookups for us to check out on our end?

Regards,

Jon
