I have taken a look through many other questions on this subject but cannot seem to fix my issue. Essentially while references display correctly I cannot get the author citation to appear in my text despite running pdflatex followed by bibtex followed by two more runs of pdflatex. Any help would be appreciated.
Sample tex file:
\documentclass{article}
\usepackage{natbib}
\begin{document}
Blahblahblah \citet*{Test12}.
\bibliographystyle{plain}
\bibliography{refs}
\end{document}
refs.bib:
@article{Test12,
author = "John Smith",
title = "Test Article",
year = "2012",
journal = "The Test Journal"
}
Output:
