okay. i removed the "sanitize" command from my get_params subroutine, and that fixed the issue. so, clearly "sanitize" is not doing what i hoped... I need to "sanitize" user input. so, in my "get_params_asHash" subroutine, I wrote: 
  my %hash = map { split(m'='x, $_, 2) }
             grep { m'='x }
             split(m'&'x, get_params());

get_params has: 
my $query = join('&', map { $_ . '=' . sanitize($cgi->param($_)) } san
+itize($cgi->param()));

and, finally, the sanitize code: 
sub sanitize($) {
  #*
  # to remove HTML from a string
  #*
  my ($s) = @_; # a string of text
  my $rv = 0;

  if ($s) {
    my $nohtml = HTML::Restrict->new();
    my $processed = $nohtml->process($s);
    if ($processed ne $s) { $rv = $processed; } else { $rv = $s; }
  }

  return $rv;
  #usage: my $sanitized = sanitize($input);
}

perhaps i'm going about "sanitizing" in "get_params" incorrectly?

I was pondering why the ball was getting bigger, and then...it hit me!
