Review all before advance

Hi Tina and welcome to the community! We just released a new feature today that allows you to easily set up conditional triggers to achieve something similar to what you're looking to do. Here's a link for more info. You can scroll down to the example to download it and see how it works. It shows how to use the trigger to have learners select all the buttons before they can navigate to the next slide. Although the next button is visible, if they haven't viewed all the content, they see a pop-up with instructions on what they need to do first. I hope that helps!
