[Koha] How to purse Subtitle of a record

[Suzon Das]

Hi,
I want to know the code of how to show the subtitle of specific biblio
number.
I tried the following but failed.


my $subtitle         = GetRecordValue('subtitle', $record,
GetFrameworkCode($biblionumber));


    $template->param(

                     subtitle                => $subtitle
    );

in opac-detail.pl.

Is there any good solution?
