Andy, there are a few things wrong with the way citations are entered in the profile.
First, you do not have sources entered above the Sources heading, but there are numbers in brackets (like "[1]") entered as text, in places that look like where you want the footnote number links to appear. You do not enter these numbers manually - they will be automatically entered by the software when the inline citations are properly entered.
Second, if you look at the edit page, you can see that all the coded inline citations are located below the Sources heading. Again, you do not manually place these where you want them to appear. You enter them in the Biography section, where you want the numbered link to them to appear. On the edit page, you have a line with the code "<references />" below the Sources heading. That is the place where all the citations will appear on the view page when they are correctly coded.
