Subsection numbering not working

I have a problem that all the subsections numbers in my report. How can I solve this problem please? I search for a solution and I try it but it also not working. this is my code:

\documentclass[12pt]{report}
\renewcommand\thesection{\color{myblue}\thechapter.\arabic{section}}
\renewcommand\thesubsection{\color{myorange}\thechapter.\arabic{section}}
\setcounter{tocdepth}{3}
\setcounter{secnumdepth}{3}
\begin{document}
\subsection{\bf\color{myorange}Overview}
\subsection{\bf\color{myorange}{Declarative Development:}}
\subsection{\bf\color{myorange}{Programmatic Development:}}


these 3 subsections shows :

1.1 Overview
1.1 Declarative Development
1.1 Programmatic Development


Anyone can help me to solve this issue?

• Welcome to TeX SX! What is the problem? You didn't explain it. – Bernard Jul 7 at 9:21
• my problem is that the subsection nembering is not working. It's showing the same number for all the subsections – sally yamak Jul 7 at 9:34
• Could you please add a minimal working example (MWE) that allows others to reproduce the issue you have? Using \documentclass{report} \setcounter{tocdepth}{3} \setcounter{secnumdepth}{3} \begin{document} \tableofcontents \chapter{Chapter} \section{Section} \subsection{Subsection} \subsection{Subsection} \end{document} I get the correct result. – leandriis Jul 7 at 9:34
• Please tell us which document class you employ. And please tell us if your document contains instructions (possibly in the preamble) that modify the properties of \thesubsection. – Mico Jul 7 at 9:41
• I edit my post can you check it please – sally yamak Jul 7 at 10:03

If I understand well your problem, it is very simple with titlesec (as you don't define myblue and my orange in your post, I had to define them myself):

\documentclass[12pt]{report}
\usepackage[svgnames]{xcolor}
\colorlet{myorange}{DarkOrange}
\usepackage{titlesec}
\titleformat*{\section}{\color{myblue}\bfseries}
\titleformat*{\subsection}{\color{myorange}\bfseries}

\begin{document}
\setcounter{chapter}{1}
\setcounter{section}{4}

\section{First section}
\subsection{Overview}
\subsection{Declarative Development:}
\subsection{Programmatic Development:}

\end{document}
