Looks like you have a hash of hashes of arrays of arrays. The principle is the same no matter how far you nest.	[reply]

`push @{$An{$n}->{b}} , $bb[$idx];` let's see, if perldsc did not make it clear enough, maybe perldata and perllol will help a bit further? Anyway, looking for "references" and Hashes of Hashes (HoH) and Hashes of Arrays (HoA) in the documentation and also on this site may help you along. What you are doing is pushing onto an array reference that is inside a hash (`%An`) of hashes the value in position (`$idx`) of an array (`@bb`). I am a little curious though: If you don't know what you are doing, why are you doing it? To see the results, do try `use Data::Dumper;print Dumper \%An;` Cheers, Sören	[reply] [d/l]

where did $An get declared? Well, I don't really understand the code fragment you posted but, maybe `print $An->{id}[0];` Try using Data::Dumper to see the contents of $An	[reply] [d/l]
