Hi There:
Trying to use variable with saveboxes and getting unexpected result. Why won't the variable show when I use the savebox?

thanks!
John

Class File (excerpt):
\let\@foo\relax
\def\foo#1{\def\@foo{#1}}
\newcommand{\showfoo}{\@foo}
\newsavebox{\testbox}
\sbox{\testbox} { Testbox goes \showfoo}

Tex File (excerpt):
\begin{document}
\foo{foo}
Test box test: \usebox{\testbox}

Show foo test: \showfoo
\end{document}

Output:
Test box test: Testbox goes
Show foo test: foo
