If I go to leave a section, I get a browser message that I am leaving the page with unsaved changes. What should I do?

Stay in that section and click SAVE (or SUBMIT).

Please note: work on one section at a time.  If you work on a section and then move to another section without saving the first section, you may confuse the browser and lose that information.  If you work on one section at a time, saving at the end of your work on that section, you should not have this issue.
