[Tex/LaTex] Can’t include appendix

Question

I'm writing my thesis and I need to add an appendix. I'm using a main file as a frame with \input for importing the single chapters.

For the appendix I'm doing this:

\appendix
\input{AppendixA.tex}

But when I try to compile the file, it doesn't show the Appendix. Any ideas of what the problem could be?

Code of the problem:

\documentclass[a4paper,12pt,twoside,openright]{report}
\usepackage[titletoc]{appendix}

\begin{document}
\title{Something}
\maketitle

\body

\chapter{Introduction}
\input{Introduction.tex}

\chapter{Conclusions}
\input{Conclusions.tex}


\bibliographystyle{splncs}
\bibliography{bibliography}


\appendix
\input{AppendixA.tex}

\end{document}

Answer 1

With the given data, I was not able, to reproduce your problem.

Maybe, there is a problem in the content of the two \includes before the Appendix starts?

I had problems with the command \body indead.

I also want to point out, that you do not need to add the .tex extension as argument to \input.

This is my MWE:

documentclass[a4paper,12pt,twoside,openright]{report}
\usepackage[titletoc]{appendix}
\usepackage{lipsum} % <--- added to get some text

\begin{document}
\title{Something}
\maketitle

\chapter{Introduction}
\input{ch3} % <--- contains only \lipsum[3-20]

\chapter{Conclusions}
\input{ch3} % <--- same as above

\appendix
\input{ch4} % <--- another \lipsum

\end{document}

I got the chapter Bar correctly in the appendix, without changing its definition, as Saravan suggested in his answer.

Maybe you'll really have to investigate in your files Introduction.tex and `Conclusion.tex?
