\end{document}

in the above latex file I have so many tests like that around 100. I used * symbol to eliminate numbering in section 3 because I am using test name with number so i am tried to add that test name and number in table of contents by using this command

Code: Select all

\addcontentsline{toc}{subsection}{1,temperature sensor.}

when I used this command I am getting errors like as I explained in above. I searched and I found some reasons why this error occurred, because of \label{} and \ref{} is not used like that. but I don't know how to use that in my file can anyone help me with that in my latex file.because I am very new and this is my frist latex file I written.

Please get used to always checking your examples for functionality and completeness. Furthermore they have to reproduce the undesired behaviour clearly and have to be reduced to only relevant content. Such examples then are called a minimal example. Your example here fulfills none of these demands. So, please catch up on that.

Furthermore it would be very kind if you mention when doing a crossposting [1]*. This is only fair because it prevents others from double efforts and waste of time.

You've got already an answer there which is qualified to solve the issue.


* According to the rules you are obliged to do so.
