Why does this bibtex entry only work with certain '\bibliographystyle's? [closed]

Question

I am using the elsarticle document class. When I compile using \bibliographystyle{plain}, all goes well. However, I want to use \bibliographystyle{model1a-num-names}. If I compile with this style I get the following kind of errors:

! Paragraph ended before \@@bibpages was complete.
<to be read again> 
                   \par 
l.171 

and

Package natbib Warning: Citation `Frary2003' on page 1 undefined on input line 
159.

I have narrowed down the problem to a single reference in my bibtex library (.bib file):

@article{Frary2003,
author = {Frary, Megan E and Schuh, Christopher A},
doi = {10.1063/1.1624490},
file = {:C$\backslash$:/Users/Ollie/Documents/Mendeley Desktop/Frary, Schuh/Frary, Schuh - Nonrandom percolation behavior of grain boundary networks in high-Tsub c superconductors - 2003.pdf:pdf},
issn = {00036951},
journal = {Applied Physics Letters},
keywords = {Nonrandom,Triple junction,percolation threshold,superconductivity},
mendeley-tags = {Nonrandom,Triple junction,percolation threshold,superconductivity},
number = {18},
pages = {3755},
title = {{Nonrandom percolation behavior of grain boundary networks in high-T[sub c] superconductors}},
url = {http://link.aip.org/link/APPLAB/v83/i18/p3755/s1\&Agg=doi},
volume = {83},
year = {2003}
}

What about this reference could be causing a problem with \bibliographystyle{model1a-num-names}, but not with \bibliographystyle{plain}?

I have tried commenting out the title and url fields, but the problem remains.

Here is a minimal working example:

\documentclass[preprint,12pt]{elsarticle}

\usepackage[nodots]{numcompress}

\biboptions{sort&compress}

\journal{A Journal}

\begin{document}

\begin{frontmatter}

\title{My Title}

\author[myaddr]{Author 1}
\author[myaddr]{Author 2}
\address[myaddr]{An Address}

\begin{abstract}
Here's an abstract.
\end{abstract}

\begin{keyword}
keyword1 \sep keyword2 \sep keyword3
\end{keyword}

\end{frontmatter}
\section{Introduction}
\label{intro}

I would like to cite~\cite{Frary2003}.

\bibliographystyle{model1a-num-names}
%\bibliographystyle{plain}
\bibliography{MyReferences}

\end{document}

And here is the log file when I try to use \bibliographystyle{model1a-num-names}:
