I have a repeating group “group_c2” where I ask for 1 family member’s name (c1_nom_fam) and 2 family member’s age (c4_edad_fam). Later in the form, I have another repeating group “group_d3” where I ask for 3 the owner of the parcel (d16_dueno). My question is, how can I set up question 3 to display a list of family members’ names (c1_nom_fam) who are older than 18 years (c4_edad_fam), and what should be the question 3 (d16_dueno) type of question?
