BibTeX, biblatex and biber ⇒ Problem with BiBTeX @electronic entry

[alpha]

Hello!

I am new to this forum as well as BiBTeX. I am writing a research paper in which I want the following citation:

Code: Select all

@electronic{xplaneworks,
  title         = "How {X}-{P}lane {W}orks",
  url           = "http://www.x-plane.com/pg_reviews.html",
  month		= "August",
  year          = "2009"
}

This generates strange errors upon compilation. If I remove "pg" from the url, like:

Code: Select all

@electronic{xplaneworks,
  title         = "How {X}-{P}lane {W}orks",
  url           = "http://www.x-plane.com/reviews.html",
  month		= "August",
  year          = "2009"
}

this works fine. Can any one help? Why is BiBTeX doing this?

I am using Texmaker under Windows XP. The error generated by Texmaker during compilation is:

Code: Select all

I've inserted a begin-math/end-math symbol since I think
you left one out. Proceed, with fingers crossed.

I've inserted something that you may have forgotten.
(See the <inserted text> above.)
With luck, this will get me unwedged. But if you
really didn't forget anything, try typing `2' now; then
my insertion and my current dilemma will both disappear.

I've deleted a group-closing symbol because it seems to be
spurious, as in `$x}$'. But perhaps the } is legitimate and
you forgot something else, as in `\hbox{$x}'. In such cases
the way to recover is to insert both the forgotten and the
deleted material, e.g., by typing `I$}'.

The underscore in the URL is the cause. This character is reserved for subscripts in math mode. In case you are using hyperref, you can use its \url command to avoid this error. The url package would be an alternative and provides the same command.


Best regards and welcome to the board

Thank you. I will try this out and get back if the problem persists.

I found a simpler way:

url = "http://www.x-plane.com/pg\textunderscore reviews.html"
