# LyX bibliography problems

I am using LyX 2.0.0.3. I am tyring to insert bibliography. I am using `plain` in the bibliography style and `article` as a document style. When I convert the document in the pdf, it shows heading "References" and then displays nothing. How can I fix this?

@PeterGrill: LyX will invoke `bibtex` implicitly if required. @user4299 (you might consider choosing a better name...): (1) Have you added at least one bibtex database (`.bib` file) in the "BibTex Bibliography" dialog? (2) Have you actually any citation in your document? –  Daniel Oct 18 '11 at 7:27
