As you never assign a value to $user your database connection attempt will fail. This will be recorded in the web server (or CGI server) error log. Always check the error log.

BTW, this:

my $sql = qq{ SELECT $fields FROM t_activ_instrument where fps_subject = '$symbol' };

is an SQL injection attack waiting to happen. Use placeholders, always.
