textbf+UpperCase title

Question

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?

Answer 1

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