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

Ohhhhh gracious ones,

I am trying to use labels in a CGI form. Is this correct? When I view the html, I do not see the labels working. Can you tell me exactly what should be done? 

use CGI;

$query = new CGI;
@letters=("a", "b", "c");
%labels=('1=>a',
         '2=>b',
         '3=>c');

print     $query->header(-title=>'some letters & labels'),
          $query->start_html('Welcome to letters'),
          $query->h1('Welcome letters'),
          $query->h3("Please select the what you would like to"),
          $query->p,
          $query->checkbox_group(-name=>'avletters',
                                 -values=>\@letters,
                                 -labels=>\%labels),
          $query->p,
          ...

    Try changing 
    %labels=('1=>a',
         '2=>b',
         '3=>c');

    to 
    %labels =( 
          1=>'a',
          2=>'b',
          3=>'c');

    Also, I recommend turning on warnings and strict.

      thanks .. it works ... but from within my script, how can I determine which selections were made by the user?
[reply]
        use CGI;
my $cgi = new CGI;

my @letters = $cgi->param('avletters');
print "The user selected: ";
print "$_\n" foreach(@letters);
