Only when I run this snippet, I get "Not an ARRAY reference at foo.cgi line 7"
$fer is a HASH reference not an ARRAY reference. You want curly brackets '{' not square brackets.

Some more advice: learn how to use Data::Dumper. This will enable you to see inside references and deep structures. The first line you print out will not be very meaningful. Data::Dumper's Dumper function will be far more useful.
