Document Classes ⇒ Problem compiling a book

[bgreen]

I’m having trouble compiling a book. I have tried to follow the structure of Stefan Kottwitz’s book. Below is code, error and questions.

Firstly, I created a preamble. It differs from the original because there are no equations/mathematics involved so I have not loaded the amsmath and amsthm packages nor included the \newtheorem or \thereoemstyle commands, but included other packages.


I didn’t include natbob or tocbind packages because I used a list instead of a formal bibliography.

Code: Select all

Run LaTeX here

and then a top level document.

[/code]\documentclass{book}
\input{preamble}
\begin{document}
\tableofcontents
\addcontentsline{toc}{section}{Title of the section}
\include{Chapter1}
\include{Chapter2}
\end{document}[/code]


When I try to compile the preamble I receive this error:

! LaTeX Error: Can be used only in preamble.

I am unsure whether the problem is the preamble, the chapter codes or the top level document?

Any advice is appreciated,

Bob

[Stefan Kottwitz]

Hi Bob,

\begin{document} and \end{document} should only be in the main file once, not in the included files.

Hello Stefan,

Thanks for your prompt reply. I removed the begin/end documents from all files except the Master document.

Initially I kept getting the same error message, however, the next day I closed Texmaker and re-opened it, the code worked.
