populating a hash key using a variable

[Ian Zapczynski]

Hello all,

I'm obviously making a silly mistake here and would appreciate it if someone can point out my error. I am trying to populate a hash of a hash in a while() loop. Here is what I have:

my $i = 0;

my %hash = ();

while (<EXPR>) {
$hash{SOMETHING}{$i} = $something;
$hash{SOMETHING_ELSE}{$i} = $something_else;
$i++;
}

The $something and $something_else strings are properly defined. If I check if $hash{SOMETHING}{$i} is defined or attempt to print it, it appears to be undefined.

How can I do what I want to do properly?
