perlanswers has asked for the wisdom of the Perl Monks concerning the following question: 

print start_form(-method=>'GET');

print " <br> &nbsp<B>Site</B> &nbsp";
$site_selected="place";

print popup_menu(
       -name    => 'popup1',
       -values  =>['place','place1','place2','place3'],
       -default => 'value2'
       -submit => 'submit'
         );
print "&nbsp &nbsp &nbsp &nbsp &nbsp  ";

print submit(-name=>'submit',-values=>'submit');
print end_form;

I had added my part of script in which here the script performs different site selection when submit button is clicked.
If i select the place site from the popup menu the place should read all the sub routines in the script and load the contents from the those subroutine
likewise the same process should happen for all other site selection also.
Now the problem is if i select site place1 the subroutines are not loading its contents for place1 it loads the previous (i.e place) contents.
By my analyses i found that the submit button is not loading its contents for different site selection
How can i load the subroutine contents different site selection onclicking submit button

    Where in your code are you fetching the popup1 parameter ?

      I had coded ad like below
      use CGI qw/:all/;
use CGI ':cgi-lib';
use CGI::Carp qw(fatalsToBrowser);
use DBI;
### Global Variables
$GLOBAL{'CURRENT_PAGE'} = self_url;
$GLOBAL{'HOME'} = $GLOBAL{'CURRENT_PAGE'};
$GLOBAL{'HOME'} =~s/\?.*//;
my %GLOBAL =();
$GLOBAL{'CONTACT_SUPPORT'} = 'filldata@gmail.com';
$GLOBAL{'CURRENT_PAGE'} = self_url;
$GLOBAL{'HOME'} = $GLOBAL{'CURRENT_PAGE'};
$GLOBAL{'HOME'} =~s/\?.*//;
print start_form(-method=>'GET');

print " <br> &nbsp<B>Site</B> &nbsp";
$site_selected="place";

print popup_menu(
       -name    => 'popup1',
       -values  =>['place','place1','place2','place3'],
       -default => 'value2'
       -submit => 'submit'
         );
print "&nbsp &nbsp &nbsp &nbsp &nbsp  ";

print submit(-name=>'submit',-values=>'submit');
print end_form;

 $site_selected = $CGI_PARAM{'popup1'};
if($site_selected =~ /^\s*$/)
{

$site_selected="place";

}

        just where do you expect $CGI_PARAM to come from? See this Re: submit button fails to pass the values using perl cgi?, i already showed you the answer. Pay particular attention to the my $ispopup1=param('popup1'); line.

        and do you realize that after you say my %GLOBAL =(); all the stuff before it 

        $GLOBAL{'CURRENT_PAGE'} = self_url;
$GLOBAL{'HOME'} = $GLOBAL{'CURRENT_PAGE'};
$GLOBAL{'HOME'} =~s/\?.*//;

        gets thrown away?

        You will avoid a lot of problems if you start your programs with 

        use strict; 
use warnings;

        And why do you persist in using two names when it is clear that both are the same clueless person?
