Hello all,

I am trying to use Data::Dumper to look at the data in a hash of hashes which looks something like: 

$hash{$w1}{$w2} =
    {
        total_counts => $tot_counts,
        words => {
                     $w3 => $count,
                 }
    }

I have tried using:

print Dumper($hash);

and all I get on the command line is:

$VAR1 = undef;

I suspect this is pretty basic, but could someone please tell me what I am fogetting? Thanks!

Update

Problem solved. This one was more than simple, it was just stupid.

Mamas: Don't let your babies grow up to be the kind of programmers who leave their 'use strict' and 'use warnings' at home when they cut and paste subroutines into test scripts outside of their mother programs!

Thanks for the help all!
