Just dereference the array in a scalar context:

#! perl use strict; use warnings; my %families = (Flintstone => [ qw(Pebbles) ], Simpson => [ qw(Bart Lisa Maggie) ], Keaton => [ qw(Alex Mallory Jennifer Andy) ]); for my $name (keys %families) { my $num_children = @{ $families{$name} }; # <-- Here's where it + happens if ($num_children == 1) { print "There is $num_children child in the $name family\n"; } else { print "There are $num_children children in the $name family\n" +; } }

Hope that helps,
