I suggest you use strict; because you would have received an error instead of nothing.

This:

foreach (sort keys %hashref) { print "$_ : $hashref{$_}\n"; }

Should be replace by this:

foreach (sort keys %{$hashref}) { print "$_ : ", $hashref->{$_}, "\n"; }

I was using a HashRef not a Hash, $hashref is not the same variable as %hashref, so if you loop through %hashref, of course you get nothing because it is an empty variable. Using strict would have prevent you from doing this. I hope this helps!

Testing never proves the absence of faults, it only shows their presence.
