Hello I have a funny (probably due to my lack of understanding of the inerds of Perl!) where I have set a global hash variable (using our), and then create some AJAX subroutines hash mappings to be exported to javascript (HTML page created via HTML::Template:Pro in the first instance). I have found that each "callback" does not persist the data to the global hash when printed in each subroutine.

Is there another way to maintain the returned values via AJAX for an HTML page with multi choice pre submission?

eg..(simple cut down for reference) 

our %myhash;

my $cgi = CGI->new();

my %funchash = ( 'SUBA'    => \&suba,

                 'SUBB'    => \&subb );


my $pjx = CGI::Ajax->new( %funchash );


my $var1="aaa";

$myhash{typea}=$var1;


my $template="html/mypage.html";

my $tmpl= HTML::Template::Pro->new(filename => $template,loop_context_
+vars=>1,debug=>1,global_vars=>1);


print $pjx->build_html( $cgi, $tmpl->output)


sub suba {

# this is invoked by user clicking on dropdown box A

$myhash{typeb}="bbbb";

print "$myhash{typea}";  <- this is shown correctly 

print "$myhash{typeb}";  <-  this is shown correctly 

} 


sub subb { 

# this is invoked after user clicked dropdown box B after A 

$myhash{typec}="cccc"; 

print "$myhash{typea}";  <- this is shown correctly 

print "$myhash{typeb}";  <-  this is _NOT_ shown 
 print "$myhash{typec}";  <-  this is shown correctly 



}
