After running
\begin{lstlisting}
pdflatex ex0001 && pdflatex ex0001

The form does not look good but contains the required functionality.

The source shows:
\begin{itemize}
\item A unique name (identifier) is assigned to each form element
using the \textit{name\/} parameter.
\item The last argument of the \textit{\textbackslash{}ChoiceMenu[]\{\}\{\}}
macro is a list containing the available choices. Each list
entry contains the full text to show and an abbreviation, separated
by ``=''.
\end{itemize}
