Carrying forward in Matrix Table?

I have a matrix table question where it asks how often x situation has happened to them in the past year (0 = None through 6 = 10+ times). There are 51 situations (statements) in the table. The following question is another matrix table asking how bothered each subject was by those situations. How do I only carry forward the statements that the subject encountered? Ex. 1. How often did you see a movie with your mom? NONE 2. How often did watch TV with your mom? 10+ times And then only carry forward #2.
