Re: Kerning

Okay, it works until I place an an argument in the stretched command.

def\MyChapterCommand#1#2{
       \framed[align=center,frame=off,width=\textwidth]{
		\vbox{
fails-->			\stretched{#2}
works-->			\stretched{This is a Test}
		}
	}
\setuphead[chapter][
   command=\MyChapterCommand
}


I get the following error when I run texexec:

! Missing \endcsname inserted.

                   \let

\stretched ... \relax \hss \relax {\hss \hss }{#1}
                                                  \egroup
...

How can I use the #1 & #2 arguments in the stretched command?
