I'm attempting a page with various examples (buttons on a page that will take them to the page with specific example), after visiting a page - i would like to give the learner to try a new example by going back to the landing page and selecting a different button that takes them to a different page, however, when i get to the page, it does not let me select anything else.  Could someone help me troubleshoot?  (I've tried setting the trigger "resets the current page" - but that doesn't seem to...

I'd like to have several buttons on my page, when learner is visiting the button i'd like the button to have a border, once its been visited i'd like to add a check mark. 

 



Please guide me.
