textbf+UpperCase title

I would like to make a section title UpperCase+textbf, however, while trying to define it like this

``````\makeatletter
\renewcommand{\section}{
\@startsection
{section}{1}{0mm}
{\baselineskip}%
{\baselineskip}
{\fontsize{14}{14}\centering\textbf\MakeUppercase}
}%
\makeatother
``````

an error is produced.

If I use only one of these two properties (`\textbf` or `\MakeUppercase`), everything works fine, so what's the problem?

Welcome to TeX.sx! A tip: You can use backticks ``` to mark your inline code as I did in my edit. –  Torbjørn T. Mar 21 '12 at 18:58

`\textbf` takes an argument (and so just gets `\MakeUppercase` as its argument here). Use the declaration form, `\bfseries` instead.
