Hello; first post on this wonderful site. I need to pass user input ($userid) from a from to the script. The script runs a system function and returns data. I am stuck, it returns nothing! Any help would be greatly appreciated. 
##Program: beta.pl

use CGI qw(:standard);
$ENV{'PATH'} = '/usr/bin:/s/sirsi/Unicorn/Bin'; $ENV{'UPATH'} = '/s/si
+rsi/Unicorn/Config/upath';

print header,
        start_html('Simple Example'),
        h1('Simple Example'),
        start_form,
        "What is your Library Card Number? ",textfield('libcardno'),p,
        submit,
        end_form,
        hr;

   if (param()) {
    $user_id = param("libcardno");
    print "Your card is: ",em(param('libcardno')),p,
$dbpin = `echo $user_id | /s/sirsi/Unicorn/Bin/seluser -iB -ow 2>/dev/
+null`;
print "Your pin is: $dbpin",
             hr;
print "<BODY>\n";
print "<HR>\n";
print "<H3>Environment Variables</H3>\n";
print "<UL>\n";
foreach $key (keys %ENV) {
  print "<LI>$key = $ENV{$key}\n";
  }
print "</UL>\n";
print "</BODY>\n";

   } 

end_html();
