How do I create Anchor Links on a page using Upfront?

I'm wondering how to create anchor links in the Upfront editor. I can see how you can set the link to an anchor point... but in the dropdown list to link to there's nothing there, and I'm not sure how to create the other end of the anchor.
The page I'm working on is here: http://test.p6solutions.co.nz/drgerald/alzheimers1/ - and basically the page has a lot of content so I want to create 'quick links' up the top that users can click to get through to the part of the article they want quicker using anchor points.
Any advice would be much appreciated
