How to overlay a box with included lstlisting

Question

i wanna have this block appear by tapping next.

\begin{block}{Methode}
\begin{lstlisting}
for i in range(2,N):
    a[i] = (a[i-1] * b + 1) % m
\end{lstlisting}
\end{block}

i tried it with

\onslide<2->{ CODE }

but i get this error message

(no line number in this file):
Package utf8x Error: Character159appearedalone.

See the utf8x package documentation for explanation.
Type  H <return>  for immediate help.
...                                              

l.23   \item<4->m sollte groß und eine Potenz von 10 oder 2 sein

thanks for your help =)

A lstlisting environment can never appear as the argument to another command. — egreg, Sep 08 '13 at 13:12

Please always post complete documents showing all packages used.

You can use \pause

\documentclass{beamer}
\usetheme{Copenhagen}
\usepackage[T1]{fontenc}
\usepackage[utf8]{inputenc}
\usepackage{listings}
\begin{document}
\begin{frame}[fragile]
\begin{block}{Methode}
\pause
\begin{lstlisting}
for i in range(2,N):
    a[i] = (a[i-1] * b + 1) % m
\end{lstlisting}
\end{block}
\end{frame}
\end{document}
