How to properly add a working table of contents

I don't have a clear understanding how to add a table of contents. I have played around and now I have two table of contents on my page. I typed in again the titles for the table of contents and now when I click on an item in the table of contents it seems to be linked to the wording that I typed at the bottom of the page. Why? and what and I not doing right? Is there a tutorial for adding the table of contents because right now I'm not finding a lot of useful help. Here is the link to my page.
