In our course we are using Storyline's default top bar buttons but with custom actions (as shown below). So for example, when the 'transcript' button is clicked, it sets the variable openTranscript to true, which in turn opens the 'transcript' layer on the slide.
This works fine on the pc when run through story.html. However when run through story_html5.html on the pc (both IE and Chrome) or on ipad (safari) the buttons simply don't work. Any ideas?
