Hello, 
Maybe somebody is able to help us here- we have a question like this (please see attachment) in our survey - people should estimate the composition of their last grocery bag. Now we would like to ask a second question which only refers to items they stated to have in their bag in this first question - all the items with zero should not be asked again - is that possible with that type of question? 

Best regards, Sandra 

Hi, Sandra,
why did you ignore the questions at the beginning.
Furthermore: you removed them.

​​​Buzzword: "subquestion relevance"

all the items with zero should not be asked again

This means,the items with a value greater 0 are asked.

Now you know how the subquestion relevance in the second question has to be.
