# Beamer error with columns

I want to put a picture in one column, some text in the other, and beneath all that some more text in a beamer style presentation. My frame looks like this:

\begin{frame}
\frametitle{Svemir dominiran tvari}
\begin{columns}
\begin{column}{0.5\textwidth}
\begin{itemize}
\flushleft{\includegraphics[width=0.5\textwidth]{btph.eps}}
\end{itemize}
\end{column}
\begin{column}{0.5\textwidth}
\begin{itemize}
\item Barionska asimetrija se izražava omjerom broja bariona i fotona
$$\eta=\frac{n_b-n_{\bar{b}}}{n_\gamma}=6.1\pm 0.3\times 10^{-10}.$$
\end{itemize}
\end{column}
\end{columns}
\begin{itemize}
\item $n_b\Rightarrow$ \quad gustoća broja (stanja) bariona\\
\item $n_{\bar{b}}\Rightarrow$ \quad gustoća broja antibariona\\
\item $n_\gamma\Rightarrow$ \quad gustoća broja fotona
$\frac{\zeta(3)}{\pi^2}g_\star T^3$
\end{itemize}
\end{frame}


When I compile it I get this error:

Something's wrong--perhaps a missing \item. \end{frame}


I looked at the code (which I c/p from another presentation that worked) and it looks the same. So why won't it compile? I have 11pt font in presentation, so that more text could fit.

Is the amount of text the issue? :\

EDIT: I have removed the itemize stuff, but now nothing shows on the slide :\

I don't see a thing on a slide now :\

You have a \begin{itemize} and \end{itemize} without an \item:

After reducing your code to a MWE by commenting out sections of code, the problem is more obvious:

\documentclass{beamer}

\begin{document}
\begin{frame}
\frametitle{Svemir dominiran tvari}
\begin{columns}
\begin{column}{0.5\textwidth}
\begin{itemize}
\flushleft{\includegraphics[width=0.5\textwidth]{btph.eps}}
% <----- There is no \item within this itemize environment
\end{itemize}
\end{column}
\end{columns}
\end{frame}
\end{document}


After adding the \item (and \RequirePackage[demo]{graphicx} since I do not have the image) with the the full code, I get:

## Code:

\RequirePackage[demo]{graphicx}
\documentclass{beamer}

\begin{document}
\begin{frame}
\frametitle{Svemir dominiran tvari}
\begin{columns}
\begin{column}{0.5\textwidth}
\begin{itemize}
\item \flushleft{\includegraphics[width=0.5\textwidth]{btph.eps}}
\end{itemize}
\end{column}
\begin{column}{0.5\textwidth}
\begin{itemize}
\item Barionska asimetrija se izražava omjerom broja bariona i fotona
$$\eta=\frac{n_b-n_{\bar{b}}}{n_\gamma}=6.1\pm 0.3\times 10^{-10}.$$
\end{itemize}
\end{column}
\end{columns}
\begin{itemize}
\item $n_b\Rightarrow$ \quad gustoća broja (stanja) bariona\\
\item $n_{\bar{b}}\Rightarrow$ \quad gustoća broja antibariona\\
\item $n_\gamma\Rightarrow$ \quad gustoća broja fotona
$\frac{\zeta(3)}{\pi^2}g_\star T^3$
\end{itemize}
\end{frame}
\end{document}

I feel so dumb right now xD Thanks, no errors this time :D Thank you very much ^^ (I'll put a right answer check in 2 minutes, apparently I clicked sth wrong and it won't let me xD) –  dingo_d May 13 '12 at 18:43
No problem. I have posted a few questions with Duh! type answers myself... –  Peter Grill May 13 '12 at 18:46
Ok, I figured out my problem. I mustn't compile with dvipdfm, I need to compile via dvips and then ps2pdf, now it works. Thanks again :) –  dingo_d May 13 '12 at 18:58
