Put references inside subsection

Question

I have tried to add a reference to an appedix inside a subsection title. When I compile it appears a ?? and there is a link to the right place but I want in the link the number of the appendix and not the ??. Am I doing something wrong?

The code is:

\subsubsection{4 Herculis \ref{fig.A.1}}

The appendix:

\appendix
\section{Espectros red 150 lin/mm}\label{ap.A}

\subsection{4 Herculis}

and the error message:

 Reference `fig.A.1' on page 32 undefined on input line 677.
 Token not allowed in a PDF string (PDFDocEncoding):(hyperref)                removing `\<def>-command' on input line 677. Token not allowed in a PDF string (PDFDocEncoding):(hyperref)                removing `\<def>-command'

Welcome to TeX.SX! Please add a minimal working example (MWE) that illustrates your problem. It will be much easier for us to reproduce your situation and find out what the issue is when we see compilable code, starting with \documentclass{...} and ending with \end{document}. — Sean Allred, Jun 21 '13 at 18:39
Seems that you have not defined a \label{fig.A.1}. If you have please show the code ... — Mensch, Jun 21 '13 at 18:45

The following example works without warnings and errors:

\documentclass{article}
\usepackage{hyperref}
\begin{document}
\tableofcontents
\section{4 Herculis \ref{fig.A.1}}
\begin{figure}
\caption{Caption of figure}
\label{fig.A.1}
\end{figure}
\end{document}

Perhaps you are using version of hyperref that is too old. The current version is 2012/11/06 v6.83m.
