FootNote Text occurs multiple times

Hi,
    The footnote text (at the bottom of the page) occurs as many times as
that footnote reference in that page. Hence if a footnote occurs twice in a
page, then the footnote text gets repeated (at the bottom of the page). How
should I tackle this problem?
   If I try to give an empty <footnote-body/> then the footnote text doesn't
display at all.
