How can I link roster question with outside roster

I have a roster whose source question is list of names from above List question. after completing the roster, there is a single select question which is bind to the roster. so that question will contain the list of names from the list question.Interviewer now has to select which person they are interviewing. now I have to enable some questions based on the information from roster of that particular person. How do I do that?

Yubraj, it looks like your linked question depends on the roster, but the roster is in turn dependent on the linked question, creating a circular dependence.

The simplest is probably to not place these extension questions in the roster at all. These questions (although asked about a person) are at the household level. See “Public example Random Demo” in which such respondent is selected randomly by the software.
