BibTeX, biblatex and biber ⇒ Referencing websites

[rms502]

Hi,
I'm trying to refernce a website and wondered if anyone could help. The website I want is: http://www.biology-online.org/4/2_water_homeostasis.htm and I'm using bibtex with a misc entry so:

@Misc{negativefeedback,
OPTkey = {},
OPTauthor = {},
title = {http://www.biology-online.org/4/2_water_homeostasis.htm},
OPThowpublished = {},
OPTmonth = {},
OPTyear = {},
OPTnote = {},
OPTannote = {}
}

But I keep on getting error messages saying I am missing $. I have an other website refernced which seems to work well so can only think that its because this one uses the character _. Is this an illegal symbol? Am very confussed
Thanks for your help.

Yes, _ is reserved for math mode for creating subscripts.

Easiest solution would be to load either the url or the hyperref package and put it as:

title = {\url{http://www.biology-online.org/4/2_water_homeostasis.htm}}

Better yet, put that under "howpublished =" or "note = ", and put the actual name of the webpage under "title". (Some bib styles even allow a url field.)
