Text Formatting ⇒ There's no line here to end

[Diebele]

I wanted to centering my sections and subsections. What should I do?
So I did this:

Code: Select all

\begin{center}
\subsection{Some subsection}
\end{center}

And received an error: "There's no line here to end"

Hi,

which document class are you using? I would suggest you to use the titlesec package (but if you are using some of the AMS document classes, it will not work).

Hi!
I use Article. Is it in AMS document class? Will try it.

No. article is one of the standard document classes; you can use titlesec without problems.
