You want something like this as the resulting LaTeX code: \begin{frame}[label={sec:org5359014}]{Comparisson} \begin{columns} \begin{column}{0.45\columnwidth} \begin{block}{Pros} % <- superfluous environment \begin{problock}{Problock} % <— argument required \begin{itemize} \item New. \item Other Pro. \item Additional Pro. \end{itemize} \end{problock} \end{block} \end{column} > #+LaTeX_Header: \newenvironment<>{problock}[1]{% The =problock= environment takes 1 argument, but you supply none. You can supply an argument #+begin_problock @@latex:{Probloc}@@ This will be ignored for non-LaTeX exporters. But even here you have to block environments, the outer environment generated by =*** Pros= and the inner problock environment. You can get rid of the outer block environment by removing :BEAMER_env: block The resulting org code will look like this: :PROPERTIES: :BEAMER_col: 0.45 :END: #+begin_problock Pros @@latex:{Probloc}@@ - New. - Other Pro. - Additional Pro. #+end_problock Greetings Axel
