I have 4 paragraphs that I want to display on a single slide. To progress, the reader selects the "Next" button. Each paragraph has a "Next" and a "Back" button to allow the reader to go either direction and read or reread the material. Once the last "Next" button is selected a "Continue" button ("Let's Take a Closer Look") is set to appear. The "Continue" button should be the only button that allows the reader to go on to the next slide. However, once the "Next" buttons have been selected more than once, the slide continues to run and goes on to the next slide. Each button has Advanced Actions assigned. I can upload those images as well. For now I've uploaded one "Next" button Advanced Action image and one "Back" button Advanced Action image so you can see how I've current set this up.
