[Koha] Syntax error in pages.pl

[Arnold]

Hi,

After following the steps to set up koha as a CMS, i followed the steps
(creating pages.pl, etc) but on testing page i created, i get the following
error;

Global symbol "$cgi" requires explicit package name at
/usr/share/koha/opac/cgi-bin/opac/pages.pl line 63
syntax error at /usr/share/koha/opac/cgi-bin/opac/pages.pl line 68, near "){"
Execution of /usr/share/koha/opac/cgi-bin/opac/pages.pl aborted due to

where line 63 is;

 my $page = "page_" . $cgi->param('p');
