Not taking away from your insight, but I think it's important for future readers of any code to see where de-referencing begins. `perl` always knows when anything in a (hash) structure is another structure and allows you to not require the deref operator (`->`) because it's implicit, but I'd recommend putting such in the path where dereferencing starts: `print "$name{$search}->[0]\n";` [download] Easier to spot where things become a reference at a glance. -stevieb	[reply] [d/l] [select]
