# Bibliography Issue apacite: Argument of \@@cite has an extra } [closed]

I am having an issue when citing references within my thesis. I use the apacite package. Below is the basic structure of the code:

\documentclass[12pt]{report}
\usepackage{apacite}

\begin{document}

\chapter{Literature Review}
Several methodological challenges arise when modeling count data (see
\cite{lord_statistical_2010} for a good review).

\bibliographystyle{apacite}
\bibliography{references}

\end{document}


This is the entry in the .bib file:

@article{lord_statistical_2010,
title = {The statistical analysis of crash-frequency data: A review and
assessment of methodological alternatives},
volume = {44},
issn = {09658564},
shorttitle = {The statistical analysis of crash-frequency data},
doi = {10.1016/j.tra.2010.02.001},
number = {5},
journal = {Transportation Research Part A: Policy and Practice},
author = {Lord, Dominique and Mannering, Fred},
month = jun,
year = {2010},
pages = {291--305}
}


However when I run the PDFLaTeX I get the following error:

error: line 0 : Argument of \@@cite has an extra }


I generate the references.bib file using Zotero software. I very recently changed the package style to apacite. Previously I had used \bibliographystyle{plain} and the references had generated as desired. But now I have hit this roadblock.

I am now clueless as to why this is happening. Any help is greatly appreciated!

Please show the entry lord_statistical_2010 of your bib file. Which document class do you use?. It's always the best providing a complete working minimal example. –  Marco Daniel Aug 25 '12 at 7:27
Sorry, but I don't get any error. –  egreg Aug 25 '12 at 10:06
When switching from one bibliography style to another, and especially when switching from one citation package to another (such as apacite), it's a good idea to wipe out all .aux, .bbl, and similar files and recompile the file from scratch, lest LaTeX and/or BibTeX get confused. –  Mico Aug 25 '12 at 10:41
Which TeX distribution do you use? Which version of bibtex and apacite? –  Kurt Aug 30 '12 at 23:25
@Kurt: Actually I found a work around to this issue. I used the natbibapa option for the apacite package and that seemed to solve all the issues. Instead of using \cite I had to use \citep for referencing. –  RazorXsr Aug 31 '12 at 5:24
