# [texhax] Newbie question re undefined control sequence

Hello

Please excuse me if this is covered in the FAQ; I did try to look, but
am not even sure what to search for.  Also, this is only my third day
using LaTeX

I am using texlive and WinEdt on a Windows machine

When I try to typeset the following

\documentclass[12pt, draft]{report}
\usepackage{graphicx, amsmath, amssymb, latexsym}

\theoremstyle{plain}
\newtheorem{theorem}{Theorem}

\theoremstyle{definition}
\newtheorem{defintion}{Definition}

\begin{document}

BUNCH OF STUFF

\end{document}

I get an error message that there is an undefined control sequence
regarding \theoremstyle

By reading the help provided in the log, and looking at Math into LaTeX
and Guide to LaTex, it seems to me that this is either due to
misspelling or not having the right package.  But I've checked the
spelling 5 times, and I thought I had loaded the right packages.

When I change report  to amsbook  I get DIFFERENT error messages, about
too many closing }.....but I've checked multiple times, and they seem to
be in pairs.

Any help appreciated

Thanks

Peter
