I would like to modify the answer that I got in this thread here such that I have the subsection numbers in the TOC but not in the text. I do not completely understand the workings of the code I was given.
Thanks
\documentclass[12pt, a4paper]{article}
**\makeatletter
\let\latexl@section\l@section
\def\l@section#1#2{\begingroup\let\numberline\@gobble\latexl@section{#1}{#2}\endgroup}
\def\@seccntformat#1{\ifcsname #1format\endcsname\else\csname the#1\endcsname\quad\fi}
\def\sectionformat{}
