How to change master slide image state when quiz question is entered correctly Oct 02, 2022 By Ben Kanspedos I'm creating a progress bar on the master slide. Throughout the module, there are 15 quiz questions. When a quiz question is answered correctly, I want the progress bar to adjust. I created 15 different States of the progress bar I created a variable "ProgressBar" with a default value of 1 When a learner answers a question correctly on the first try, I want to adjust ProgressBar by a value of 1. But I can't do this because Storyline only allows you to adjust a variable to a specific value. I don't see an option to adjust the variable by +1. Maybe I'm taking the wrong approach, please help. Thanks!
