ifthenelse inside a caption

[kipibenkipod]

Hi,
I'm trying to use this simple code:
\caption{\ifthenelse{\equal{1}{1}}{1}{2}}

and I get:
! Undefined control sequence.
<argument> \equal

I use this ifthenelse in another newcommand and use the newcommand in
the caption.
Searching the net didn't give much.
What should I do in order to solve this?

Thanks,
Kfir

undefined control sequence? have you loaded the ifthen package?

anyway, \caption is a fragile command, so i doubt it likes what
you're trying to do. however, if you use the optional argument as
well, perhaps your problem will disappear. (how complicated is your
real example?)

this works for me:

\documentclass{article}
\usepackage{ifthen}
\begin{document}

\begin{figure}
\caption[toc entry]{\ifthenelse{\equal{1}{1}}{1}{2}}
\end{figure}

\end{document}

cheers,
jon.

Solved!
Thanks Jon.
My problem was a bit more complicated, but I just added the optional
argument to \caption and now everything works fine.
I really appreciate your help.
Thanks,
