Thank you for the Perl data structure cookbook. Your code did not work but it sure gave me a place to look how to solve this. Since this was nested I needed to refrence it with arrows. Thanks so much for your help. I am bookmarking this link too. Here is the code that worked. `print $Data->{logins}->[0]->{url};` [download]	[reply] [d/l]

Only the first (leftmost) arrow would make a difference, the others are always optional (as they don't help to disambiguate — those are always references). In other words, you also could've written: `print $Data->{logins}[0]{url};` [download]	[reply] [d/l]
