The "Passing Score" field in the RESULT TOOLS DESIGN ribbon is connected to the "Passing Score" field in the Quiz Settings window.
In my file, when I edit one field, the other field is automatically updated (which is how it's supposed to work).
@A.R. Chao: If the fields aren't updating each other correctly, it's possible that the Results slide is corrupted. I suggest you delete that Results slide, and insert a new one.
If the fields are properly connected in the new Results, the problem was in the slide. However, if the problem persists, I suggest you contact the Articulate support staff directly. You can do that here: Contact Support for Help with Any Articulate E-Learning Course Development Software
