I have three consecutive questions, each of which builds upon the other:
1) What types of surgeries do your patients receive?
2) [For the types of surgeries that your patients receive], which do you perform and which do you refer?
3) [For the types of surgeries from #2 that you refer], to what type of physician do you refer?
I understand that #2 is based on the parent list from #1 (that code works). However, for question #3, I cannot figure out how to populate the rows of a grid question with the responses from #2. Do I need to create a sub parent list?
This feels like it should be straightforward but I cannot figure it out. Any suggestions?
