Footer as a Hyperlink

[ssutcliffe]

I am trying to create a link at the bottom of an ongoing 77 page word document. The link should be fixed on every page at the bottom and should hyperlink to the bookmark at the begining of the doc called "top" to bring the user to the begining of the page. I have tryed using the footer as a hyperlink but when I close the footer the link wont work. Any suggestions on how to create a fixed hyperlink on the bottom of every page that wont move when new text is added above it?
