I'm using the class beamer to prepare lectures. I want to make a
reference to a formula given in last week's lecture, but I get only
question marks.
Example input:
\documentclass[handout]{beamer}
\includeonlylecture{week 2}
\begin{document}
\lecture{lecture 1}{week 1}
\begin{frame}
\begin{equation}
\label{eq:test}
1=1
\end{equation}
\end{frame}
\lecture{lecture 2}{week 2}
\begin{frame}
\begin{equation}
\label{eq:test2}
2=2
\end{equation}
equation(\ref{eq:test}) and (\ref{eq:test2})
\end{frame}
\end{document}
equation number 1 is correctly counted when calculating the number for
the second equation, but I did not manage to get acces to \ref{eq:test}.
Any hints?
thanks
Martin

Assuming you compiled the slides from week one with the jobname "test", you could do
