To refer to something somewhere else in your document, you first have to label it using the \verb+\label{}+ command:\label{example1}
\begin{Verbatim}
This is a line of text. \label{example1}
\end{Verbatim}
To refer to it, you can use \verb+\ref{example1}+. This will insert either the section number, the page number, the equation number, or the figure number, depending on what you attached the label to.
If you \textbf{must} refer to a page number, use \verb+\pageref{example1}+.
\begin{Verbatim}[frame=lines,framesep=3mm, breaklines=true, label=\fbox{Cross-Referencing Example}]
Internal references (i.e., cross-references) are explained in section \ref{example1} on page \pageref{example1}.
\end{Verbatim}
