Hi Monks!

My perl code here should get some parameters from my html template, but I can't figure it out why I can't get the parameters sent back from the HTML to print after a click on the button(s) on the form. I can see the parameters been passed, by the perl ignores it.
Can someone help on that? Or explain why this is happening?

The Perl code
#!/perl/bin/perl

use strict;
use CGI qw/:standard/;
use CGI::Carp qw(fatalsToBrowser);
use DBI;

my $q = new CGI;


print header();
#print "Test";
my $userip = $ENV{'REMOTE_ADDR'};
#print $userip;
my $curr_dir;
#print $userip;

# Grab the current directory from $0. 
BEGIN
 {
  $0 =~ '(.*[\\\/])\w+\.\w+$';
  $curr_dir = $1 || "./";
 }

my $display = &filter($q->param('display')) || '';
my $insert = &filter($q->param('insert')) || '';
my $confir = &filter($q->param('confir')) || '';

my %AoH;


if($insert eq "insert"){
$AoH{MESS} = "OK your message has been received!";
}else{
$AoH{MESS} ="";
}

print "<br><b>I must to print these values here once the buttons on th
+e form has been clicked:</b><br>***INSERT=$insert******DISPLAY=$displ
+ay******CONFIR=$confir######<br>";

my $out_file;

$out_file = "${curr_dir}table.html";
open(OUTPUT, "$out_file") || print "L40 - There is no file here, I'll 
+run away now!";
while(<OUTPUT>) {

        $_=~s/<!-- (\bMESS\b)\/\/ -->/$AoH{MESS}/g;

    print  $_;
    }

close OUTPUT;
