I'm very confused about your coding. 

my $filter = "filter";   # I'm a scalar here..

and then later in your code: 
$hash{$filter[$c]->[4]}    # or am I an array?

besides which you are putting the above in a pair of single quotes 
'$hash{$filter[$c]->[4]}'   # that will literally be "$hash{$filter[$c
+]->[4]}"

not cool.

Start your script off with use strict; and you'll see helpful information.
