I apologize if I am over-explaining this, but relevance is like an if/then situation. If the items in your custom expression are truly then this item (prompt/question) is relevant to display. For example, the first element in the former might be the question named "alone" with the label "Are you the only person at this address?" There are two answers possible "yes" and "no". The next element would be the question named "number" labeled "How many people live here?" It is only relevant to display the label "How many people live here?" and a place to write the answer for the item named "number" if the answer to the item named "alone" equals "no". So your item named "number" won't appear if you answered "yes" to the question in the label for the item named "alone." An example formula for relevancy for the item named "number" would be

selected(${alone},'no')

If the item named "alone" was a selection tool. You could do other things like range of age in a text prompt.

Hope that helps.
