I'm finishing up a simple registration form and am running into some difficulty handling a redirect. In my case, there is a final "submit" input that passes a hidden session value that is used to gather user data from the database. This non-sensitive data then requires two actions:

1) An email is generated to the "owner" with the contents of the "order".

2) The user is redirected to PayPal, along with a series of hidden form values.

The first requirement is successful, but the second is causing errors. I've never attempted a redirect with CGI, much less one with hidden form values, so it's quite likely I'm screwing the pooch. In its current state, it results in the following Apache error: 
malformed header from script. Bad header=HTTP/1.1 302 Moved: index.cgi

Here's the relevant sub. If anyone has any ideas, I'd love to hear them. Thanks! 
sub paypal_redirect {
        my ($query, $total_cost) = @_;
        my $cgi = CGI->new;
        print $cgi->redirect(-uri => 'https://www.paypal.com/cgi-bin/w
+ebscr', -nph => 1);
        print $cgi->start_form(-method => 'post');
        print $cgi->hidden(-name => '_cmd', -value => '_xclick');
        print $cgi->hidden(-name => 'business', -value => $email);
        print $cgi->hidden(-name => 'item_name', -value => $comment);
        print $cgi->hidden(-name => 'item_number', -value => $query->p
+aram('session'));
        print $cgi->hidden(-name => 'amount', -value => $total_cost);
        print $cgi->hidden(-name => 'no_note', -value => 1);
        print $cgi->hidden(-name => 'currency_code', -value => 'USD');
        print $cgi->end_form;
}
