# sidewaysfigure does not work [closed]

I am having trouble with 'sidewaysfigure'. It simply isn't recognized and says ' Missing number, treated as zero'

my code is

\begin{sidewaysfigure}[hbtp]
\setlength{\abovecaptionskip}{0.01pt} % Chosen fairly arbitrarily
\centering
\includegraphics[width=\paperwidth-3cm,height=\paperheight-3cm]{cd4neutral.eps}
\caption{Variables in \textbf{CD4}-dataset}
\label{cd4neutral}
\end{sidewaysfigure}


and my preamble

\usepackage{latexsym}
\usepackage{amsfonts}
\usepackage{amssymb}
\usepackage{amsmath}
\usepackage{amsthm}
\usepackage{fancyhdr}
\usepackage{setspace}
\usepackage{graphicx}
\usepackage{epstopdf}
\usepackage{tabularx}
\usepackage{multirow}
\usepackage[version=3]{mhchem}
%   \usepackage{chemarrow}
%   \usepackage{array}
\usepackage{float}
\usepackage{subfigure}
\usepackage{subfloat}
\usepackage{listings}
\usepackage{dsfont}
% indexing
\usepackage{makeidx}
\usepackage{nomencl}
\usepackage{float} % needs to be "fixed" by hyperref
\usepackage{placeins} % float placement, defines \FloatBarrier
\usepackage{setspace}
\usepackage{txfonts}
\usepackage{booktabs}
\usepackage[toc,page]{appendix}
\usepackage[T1]{fontenc}
\usepackage{titlesec, blindtext, color}
\usepackage{pdflscape}
\usepackage{lscape}
\usepackage{rotating}
\usepackage{epsfig}
\definecolor{gray75}{gray}{0.75}


does anyone see why this isn't working for me??

Welcome to TeX.sx! A tip: If you indent lines by 4 spaces or enclose words in backticks , they'll be marked as code, as can be seen in my edit. You can also highlight the code and click the "code" button (with "{}" on it). –  topskip Apr 9 '13 at 5:12
sidewaysfigure has no optional argument. However, create a complete example document which shows the error. With your preamble and your example code it works for me. –  Herbert Apr 9 '13 at 6:36
Please always post a complete (small) document that shows the problem. Your preamble shows some strange things but nothing that would generate an error. don't load epsfig (use graphicx) don't load lscape and pdflscape don't load setspace twice no ned to load amsfonts as you load amssymb –  David Carlisle Apr 9 '13 at 7:02
note that you might surprise yourself with \includegraphics[width=\paperwidth-3cm,height=\paperheight-3cm]{whatever} inside a sidewaysfigure environment; the width and height settings aren't changed inside a sidewaysfigure, so your settings should take account of the rotation: \includegraphics[width=\paperheight-3cm,height=\paperwidth-3cm]{whatever}` –  wasteofspace Apr 9 '13 at 11:22
