I am trying to get the instant payment notification module on paypal to work with my server. I have this script running fine on regular transactions, but on subscriptions it doesn't work. PayPal said that the subscriptions engine that interacts with the database is pickier than the standard one, and that it only accepts the variables from your script if they are in the same order that was sent. I can't seem to get them to be in the same order as they were sent to me. Any ideas? 
#!/usr/bin/perl

my $query='';
my @inp=split(/\:/,$input{input_fields});
foreach my $ikey (@inp){
    next if $ikey=~/inview|cid/is;
    $query .= "\&$ikey=$input{$ikey}";
    }
$query .= '&cmd=_notify-validate';
# post back to PayPal system to validate (in same order as they passed
+ it to us)
use LWP::UserAgent;
$ua = new LWP::UserAgent;
$req = new HTTP::Request 'POST','http://www.paypal.com/cgi-bin/webscr'
+;
$req->content_type('application/x-www-form-urlencoded');
$req->content($query);
$res = $ua->request($req);
my $result='';
if ($res->is_error) {
    $result='HTTP Error';
    print 'HTTP Error\n';
    }
else{
    $result = $input{payment_status};
    }
print "\nRESULT:$result\n";
