here is a walk through screenshot of how to get it to work.
go to your profile then click on the about me tab.
I would recommend right click on either your name or at the top profile that way you have a tab for the walk through and a tab open to work in.
this will allow you to switch between the 2 ( two ) screens. At any point if you are not sure all you need to do is look at the tab with the walk through to make sure you have it correctly.
