Progress bar keeps updating while revisiting the pages

Hi,


1. I have used a progress bar (lactora object) in a course. When the course progresses the progress bar works fine.

When I navigate the pages that I have already visited using back button, still the progress bar updates and shows the bar width decreases.


Fox example, once I navigate all the pages, the progress bar shows completed, but if I revisit any pages then again, the progress bar keeps updating.


I do not want the progress bar keep updating again and again while revisiting the pages.


Could anyone help or suggest me how do I go about this.? Thanks !!



2. I want to show the course progress in percentage right below the progress bar.


For ex: You have completed : xx %


How do I get this done.? Any help in this would be greatly appreciated. Thanks!!
