Custom layout with comment field included

Hi. We would like to have an export that prints out also the \comment{} field.
I tried to download the layout files and modified the Chicago.biblio.layout adding at the end, where it was:

(\year).
\begin{note}
, \note
\end{note}
.
\\par
\\par

the corresponding (I think) part for the comment, i.e.

(\year).
\begin{note}
, \note
\end{note}

\begin{comment}
, \comment
\end{comment}

.
\\par
\\par

It does not work: the output is the same as before (and I have a couple of entries in the bbibtex that are with comments as follows

comment = {This is an example comment},

).
Thanks for any help
