Returning to a slide

Hi. We have test questions. On each question page is a "get help" button.  I have it set 2 different ways - 1 - the "help page" plays and then sits there until the student clicks another button - "return to question" AND 2 - the "help page" plays and then automatically returns after a period of time - automatically, or if they click the "return to question" button.  PROBLEM - If the student wants to return to the "help page" a second time - he can't.  And even on the pages where there is no audio that plays - once he leaves the "help page" - he can't really return.  I want them to be able to click the "get help" button - go listen to/look at the "help page", click the button to return to the question page (or after a period of time elapses) - BUT be able to return to the "get help" page again if they need to.  It doesn't have to automatically play the audio the second time.  Can someone help me with how to set this up? We are using Articulate Storyline 3.
