General ⇒ own environment inside environment: forgotten \endgroup.

[talas]

Hi,

I try to create my own envrionement in LaTeX2e, where it want to have a envrionment inside environemnt (see the example).

Code: Select all

\documentclass{article}

\title{title}
\author{author}
\date{}

\newenvironment{Inside}[2]{%
  #1 & #2 &%
}{%
  \\%
}

\newenvironment{Outside}{
  \begin{tabular}[t]{lll}
    \textbf{1} & \textbf{2} & \textbf{3}  \\
}{
  \end{tabular}
}

\begin{document}

\begin{Outside}
\begin{Inside}{AAA}{BBB}
descriptive text...
\end{Inside}
\end{Outside}

\end{document}

But all I get is this error message:

Code: Select all

This is pdfTeX, Version 3.1415926-1.40.9 (MiKTeX 2.7)

                          \hskip \tabcolsep \endtemplate

Does some one know how I can fix this problem?

Thanks in advance.
