footnote

Hi all,
I’m trying to make a pdf of an article with some footnotes but there is a problem: the footnote is printed (also) in pdf, following the word with the note number…
Is there a special footnote plugin you can indicate ora a workaround with css etc?
I can change if needed…
Thanks, as always, in advance.
