Compiling LaTeX via an on-line server

I have a LaTeX text document that compiles fine with the current version of pdflatex on my home computer. I've made minor edits to the body of the document. I'm trying to recompile it, using either http://sciencesoft.at/latex/?lang=en or the first google result for the words "latex to pdf online." (I can't post the hyperlink due to spam prevention.) The former site is running pdfTeXt; the latter, MikTeX. I've pasted my headers below. Does anyone know how I might change them to make either one work?

Thanks,

\documentclass{article}

\usepackage{setspace}

\pdfpageheight 11in

\pdfpagewidth 8.5in

\doublespacing

\usepackage[top=1in,bottom=1in,left=1in,right=1i开发者_如何学Pythonn]{geometry}

\usepackage{fancyhdr}

\pagestyle{fancy}

\headheight{15pt}

\fancyhead[R]{My name}

\fancyfoot[C]{\thepage}

\begin{document}

\section*{Finite Simple Groups}

...text...

\end{document}

Looking at the output, I saw the problem was with the \headheight command. Googling for that suggests you should change it to \setlength\headheight{15pt}. This makes it work with the sciencesoft tool!
