# “Missing number” error with SCfigure (from sidecap package)

Does anyone know how to do "side captions" in LaTeX if you already have a caption environment specified? I keep getting an error when I use SCfigure.

Ex:

\documentclass{article}
\usepackage{sidecap}

\begin{document}
\begin{SCfigure}[h!]
\centering
FIGURE
\caption{CAPTION}
\label{conforms}
\end{SCfigure}
\end{document}

Welcome to TeX.sx! Please add a minimal working example (MWE) that illustrates your problem. –  lockstep Jan 17 '12 at 22:45
And don't let the name "working example" fool you - it may also be a non-working example. –  Michael Palmer Jan 18 '12 at 4:46
Note that you don't have a \begin{document}...\end{document} in your MWE. –  Werner Feb 7 '12 at 21:03

SCfigure has two optional arguments. If you use the second one, you must also use the first:
\begin{SCfigure}[\sidecaptionrelwidth][h!]
