I have problem with creation of table contents. A part of my code:
\documentclass[a4paper]{amsbook}
\usepackage[cp1250]{inputenc}
\usepackage{polski}
\makeatletter
\renewcommand*\@seccntformat[1]{\csname the#1\endcsname.\enspace}
\makeatother
\usepackage[sf,bf,outermarks]{titlesec}
\begin{document}
\tableofcontents
\chapter*{Introduction}
\chapter{(Chapter 1 - Title)}
\section{Section - Title}
\section{Section - Title}
\subsection{Subsection - Title}
\subsection{Subsection - Title}
\section{Section - Title}
\section{Section - Title}
\section{Section - Title}
\subsection{Subsection - Title}
\subsubsection{Subsection - Title}
\subsubsection{Subsection - Title}
\subsection{Subsection - Title}
\subsection{Subsection - Title}
\section{Section - Title}
\begin{thebibliography}{1}
\bibitem{1} Bibliography 1
\end{thebibliography}
\end{document}
and it shows like this
as you can see, text overlapping.
How can I change this?
How can I add the number of chapter before number of section?
[ Chapter 1. Title
1.1 Section title
1.2 Section title
....
Chapter 2. Title
2.1 Section title
2.2 Section title
...]
