graphics in style file

Question

I aim to create a reporting template for other TeX users to use at our work. My objective is creating an .sty file. The specifications are fairly simple but one is causing grief: that is including our logo in the upper left for a header. I've used the fancyhdr program to create a fancyhead like the following:

\RequirePackage{fancyhdr}
\fancypagestyle{everypage}{
    \fancyhf{}
    \fancyhead[R]{\includegraphics{LOGO.JPG}}
  \fancyhead[L]{\huge{Report name} \\ \normalsize{\today}}

  \fancyfoot[L]{XXX}
  \fancyfoot[C]{YYY}
  \fancyfoot[R]{ZZZ}

  \renewcommand{\headheight}{.5in}
  \renewcommand{\textheight}{6in}
}
\pagestyle{everypage}
\AtBeginDocument{\thispagestyle{everypage}}

But when compiling a tex document with this, I get the following error:

[Loading MPS to PDF converter (version 2006.09.02).]
) <LOGO.JPG, id=1, 154.6578pt x 51.0708pt> <use LOGO.JPG>
! You can't use `the character .' after \the.

Any idea what's going on here?

Answer 1

When modifying lengths, use

\setlength{\headheight}{.5in}

not \renewcommand. Also, consider setting document elements affecting the page margins/size via geometry.
