# Chapterstyle in memoir

For some reason I can't compile the following small example in memoir.

\documentclass[oneside,12pt]{memoir}
\begin{document}

\frontmatter
\tableofcontents
\mainmatter

\chapter{First chapter}
Text
\chapter{Second chapter}
More text

\end{document}


Gives the following error:

! Undefined control sequence.
<argument> \hspace {0.4em}\resizebox
{!}{4ex}{\chapnamefont \bfseries \sffam...
l.13 \mainmatter


If I comment the line \chapterstyle{madsen} the document compiles well. I have used \chapterstyle{madsen} in other documents before. Why is it that I can't compile this one?

Add \usepackage{graphicx}, as explained in the manual, p. 94, where the chapter style madsen is described. –  egreg Mar 25 '12 at 22:24
Thanks @egreg, that fixed it! If you want to rewrite that as an answer, I"ll accept it. –  user815423426 Mar 25 '12 at 22:28

The description of the madsen chapter style on p. 94 of memoir's manual specifies that
\usepackage{graphicx}
