Notes on making the LaTeX markup language do what you want it to do.

• use pdflatex(1) to create PDF files. See the PdfLatexNotes page for more.

  • alternately, you could use LaTeXpdf (which is a different method for making PDFs from LaTeX).
• Here is a really good online HTML doc about LaTeX commands

Here is a command that lets you do different things with numbers depending on their magnitude.

\newcommand{\formatnumber}[[1]{
  \ifnum#1=0 {\bf zero} \else
  \ifnum#1<2 {\bf one} \else
   {\bf two or more}\fi
  \fi
}

I got this message when I had a figure at the start of a \subsection with no text before it. Moving the figure down a bit so that some text appeared before it in the input file fixed this.
