This line is incorrect.

As
use strict;
would have told you.
The problem is that the
my $hidden = @_;
sets $hidden to the number of elements in @_. Not to the first
parameter passed to FormElements().
So the $$hidden doesn't access the global $hidden variable, but a
variable whose name is the number.
Try to print the $hidden inside the subroutine!
You want either
my ($hidden) = @_;
or
my $hidden = shift(@_);
