In LyX, I'm using the reference style apsrev.bst, which I downloaded from here:
http://www.maik.ru/pub/tex/revtex4/
This reference style is the one used in Physical Review.
But now when I add references, they show up as question marks in brackets (?).
Why does this happen? how can I fix it?
Thank you for any efforts
apsrevstyle is part of TeX Liveit seems, as I could choose it in the bibliography window without downloading. I then used one of the.bibfiles already listed in LyX (xampl.bib) and added a couple citations (Insert --> Citation) from it to the document. After compiling with Ctrl + R everything shows up fine. – Torbjørn T. Jun 2 '12 at 13:12
