Hi, I've always had a problem with getting my modules to pass their subroutines as callbacks. Does anyone know the correct structure? 

package WebUtil;

sub Gen_HTML
{ 
  my $self = shift; 
  
  # 
  # Do stuff to make html 

  $self->{$HTML} .= qq( html content stuff ); 

  return($self->{$HTML}); 
} 


sub run_pjx 
{ 
  my $self= shift; 
  my $pjx = new CGI::Ajax( 'exported_func' => sub
                                                 { 
                                                      my $in = shift; 
                                                      return("Changed 
+Main $in\n"); 
                                                 }, 

                              'skip_header'   => 1  
                         );  
  my $ref_Gen_HTML = sub { $self->Gen_HTML() }; 
  print $pjx->build_html( $self->{$WU_CGI} , &$ref_Gen_HTML ); 
  #note should be:   build_html( $cgi_object, \&callback_Function );  

}
