Sorry it is unclear. I have something kind of working,but not really working. When I click on the Update button, I see my post appear on the screen (ie., healthchk.cgi?fname=displayText&args=Update&update=Update) for a second and then it flashes off the screen instead of the text I was expecting from the &displayText function. Here is part of the code: 
#!/usr/opt/perl5/bin/perl -Tw

use CGI;
use CGI::Carp qw(warningsToBrowser fatalsToBrowser);
use CGI::Ajax;
use strict;
use warnings;
use English;

use Env qw(PATH IFS CDPATH EMV BASH_EMV);
$ENV{PATH} = "/bin:/usr/bin:/usr/local/AppAdmin/healthchk/bin:/usr/loc
+al/healthchk/bin";
delete @ENV{ 'IFS', 'CDPATH', 'ENV', 'BASH_ENV' };

my $home = "/usr/local/AppAdmin/healthchk";

my $html = "";
my $cgi = CGI->new();
my $ajax = CGI::Ajax->new(displayText => \&displayText );
$ajax->JSDEBUG(1);
print $ajax->build_html($cgi,\&main);

sub main() {

        $html = <<HTML;
