latex \renewcommand trouble

[Shao Zhang <shao@linuxfreak.com>]

Hi,
	I am tring to redefine the subsection in latex using the
	renewcommand. I use the following code:

	\renewcommand{\subsection}{\@startsection
	{subsection}%
	{2}%
	{0mm}%
	{0.5\baselineskip}%
	{0.5\baselineskip}%
	{\normalfont\normalsize\itshape}}%

	But when I use it with something like \subsection{hello}

	I got the following error:

	Document Class: article 1999/01/07 v1.4a Standard LaTeX document
	class
	(/usr/share/texmf/tex/latex/base/size12.clo)) (hello.aux)
	! You can't use `\spacefactor' in vertical mode.
	\@->\spacefactor 
        \@m 
	l.29 \subsection
			{hello}
	? 

	Please help me with this.

	Thanks in advance.
Shao.
