What specifically connects a List Dynamic Page to an Item Dynamic Page?

Created a Collection and then generated the List and Item pages separately. Added a button to the List page for each item and set the “Click action connects to” setting the Item Dynamic Page. When I preview or go to the live site, nothing happens when I click the button (the Item Dynamic page I specify doesn’t load). I also don’t see any error or exception information. Is there some other linkage that needs to be established? Someone in another forum asked about the pages’ URLs. Is there some naming convention that has to be followed?
