problem with appendixes

[Pawel_Iks]

I want to place two appendixes in my document, and when I use
following code:

\appendix
\chapter{Sth 1}
\label{ch:appendixA}

...

\appendix
\chapter{Sth 2}
\label{ch:appendixB}

...

both of these appendixes are shown as A in my table of content. And I
have problem with labeling them. When I place \ref{ch:appendixA} in
output appear ?? instead of diserable text.

I want to number equations as A-1, A-2, ... in first appendix and B-1,
B-2, ... in second. I use for this command

\renewcommand{\theequation}{\thechapter--\arabic{equation}}

which somebody from this forum advise me, but I don't understand: if I
have to write this command in all appendix or only once? Now,
equations in both appendixes are numbered as A-1, A-2, ...

Where is the problem?

Hi,

remove the second \appendix... you only need it once.

Pawel_lks,

This is how i solved my problem with appendix to create two
distinct chapters: one for appendices and the other for annexes.


\titleformat{\chapter}[block]{\raggedright\Huge\bfseries}
{\chaptertitlename~\thechapter\space-\space}{0em}{} %%
\usepackage{titlesec}
\begin{appendices}
\appendix
\include{<appendix_chapter1>}
\include{<appendix_chapter2>}
\renewcommand{\appendixname}{Annex}
\newcounter{countannex}
\setcounter{countannex}{1}
\renewcommand{\thechapter}{\Alph{countannex}}
\include{anex_chapter1}
\end{appendices}


----//----

-----------------------------
appendix_chapter1.tex
-----------------------------

\newcounter{fig.appendixA}
\setcounter{fig.appendixA}{0}
\renewcommand{\thefigure}{\Alph{chapter}-\arabic{fig.appendixA}}
\chapter{Appendix Chapter} \label{ch:appA}
Ipses datum gertum...

\addtocounter{fig.appendixA}{1}
\begin{figure}
\end{figure}


----//----

-----------------------------
appendix_chapter2.tex
-----------------------------

\newcounter{fig.apendiceB}
\setcounter{fig.apendiceB}{0}
\renewcommand{\thefigure}{\Alph{chapter}-\arabic{fig.apendiceB}}
\chapter{Second Appendix}

%same as above to figures

----//----

-----------------------------
annex_chapter1.tex
-----------------------------
%same ideia of the appendices

Good luck,
Márcio

P.S.: You may find mistakes on variables name, 'coz i have translated
it.

As suggested by Luis, remove the second \appendix command from your
LaTeX code. Then your appendices should be sequentially labelled
Appendix A
...
Appendix B
...
etc.

I'm not sure why you received a '??' in your output. Did you remember
to compile twice?

Also, you only have to use the
\renewcommand{\theequation}{...}
once to change the way you will reference and label equations. The
labelling change will occur from the location you place the command
onward.
