Hello! I saw you made an edit to Human Development Index, and it appears you tried to add a reference. The way you did it did not work properly, however, but don't worry about it! This guide can help you learn how to add a citation properly to an article. If you were trying to just add an external link directly, there is an external links section at the bottom of the page.
