Tried adding an if statment to check value but am still erroring out with "Can't call method "value" on an undefined value at vote.pl line 14." line 14 is the if statment.

#!/user/perl

use strict;
use DBI;
print "Content-type: text/html\n\n";

+Vote, $value, $c);
$filename = param('name');
$rating = param('rating');
%cookies = fetch CGI::Cookie;
$CanVote = 1;
@VotedOn = '';
if ($cookies{'FFInfoVotedOn'} -> value) {
    @VotedOn = $cookies{'FFInfoVotedOn'} -> value;
    foreach $value (@VotedOn) {
        if ($value eq $filename) {
            $CanVote = 0;
        }
    }
}
