I suspect you're off by a couple of lines:
my @names = $q->param;
my $params = Vars;
my $len = @{$params}; # $params should be a hashref
Vars() returns a hashref, not an array ref. Also, if you're going
through the trouble of fetching the param() list, why use Vars? Vars
is to provide compatability with old cgi-lib scripts. Becuase it
separates values with null bytes, you run the risk of exposing you code
to a security hole known as the "null byte hack". I explain the latter
in lesson three of my CGI course:
