Need a little help with this one

All,

I have a file /var/www/cgi-bin/tryit.cgi:


#! /usr/local/bin/perl
# tryit.pl

use Acrobat::FDF;

$inFDF=new Acrobat::FDF('-',$ENV{'CONTENT_LENGTH'});

my $currentField;
my $currentValue;

print("Content-type: text/plain\n\n");

$currentField=$inFDF->NextFieldName("");
while($currentField)
{
    $currentValue=$inFDF->GetValue($currentField);
    print("Current field: $currentField  CurrentValue: $currentValue\n");
    $currentField=$inFDF->NextFieldName($currentField);
}

exit 0;

Serving with the Apache 2 server (2.0.40), I have a pdf file that calls
tryit.pl when its submit button is pressed. It processes the fdf output
from the pdf file:

Current field: dbName  CurrentValue: QuizIt
Current field: dbTable  CurrentValue: Math101
Current field: Quiz1.numCorrect  CurrentValue: 1
Current field: Quiz1.numQuestions  CurrentValue: 3
Current field: Quiz1.Responses  CurrentValue: a,a,a
Current field: quizName  CurrentValue: Quiz1

Now, shut down the Apache 2 server and start up Apache 1.3. Place the same
tryit.cgi in /usr/local/apache/cgi-bin, adjust the submit path in
Quiz1.tex,recompile to Quiz1.pdf, then call:  

http://scinux.redwoods/online_testing/Quiz1.pdf

Again, all is well:

Current field: dbName  CurrentValue: QuizIt
Current field: dbTable  CurrentValue: Math101
Current field: Quiz1.numCorrect  CurrentValue: 1
Current field: Quiz1.numQuestions  CurrentValue: 3
Current field: Quiz1.Responses  CurrentValue: a,a,a
Current field: quizName  CurrentValue: Quiz1

Now, move tryit.cgi to
/usr/local/apache/htdocs/online_testing/perl/tryit.pl. Adjust the submit
path in Quiz1.tex, recompile to Quiz1.pdf, then call:

http://scinux.redwoods/online_testing/Quiz1.pdf

We now get the error:

<!DOCTYPE HTML PUBLIC "-//IETF//DTD HTML 2.0//EN">

And:

[EMAIL PROTECTED] apache]#tail logs/error_log
[Sat Jul 10 20:04:42 2004] [error] Can't call method "NextFieldName" on an
undefined value at /usr/local/apache/htdocs/online_testing/perl/tryit.pl
line 13.\n

In my httpd.conf, I've done this:

Alias /online_testing/ "/usr/local/apache/htdocs/online_testing/"
<Location /online_testing/>
        AuthName OnlineTesting
        AuthType Basic
        PerlAuthenHandler Apache::AuthAny
        require valid-user
        PerlAccessHandler Apache::GateKeeper
        PerlSetVar Gate open
</Location>


<Directory /usr/local/apache/htdocs/online_testing/perl/>
        SetHandler perl-script
        PerlHandler Apache::Registry
        Options +ExecCGI
        PerlSendHeader On
        allow from all
</Directory>

Does anyone know why it won't work in this last configuration?
