Perl flattens lists automagically, so when it sees your C<%modules,
%settings> it flattens it to one list of key value pairs, or actually
just an ordered list of values. Conveniently when you are assigning a
list to a hash Perl is smart enough to switch the ordered list back into
key/value pairs, however the problem and the reason the above won't
work, is that Perl keeps gobbling until the end. So your two lists, get
flattened into 1, and remain flattened with all of the values going into
%modules. This is most commonly avoided by passing references to the
two lists into the sub, then you can dereference them back into
lists/hashes if you like. So,
Navigate(\%modules, \%settings);
sub Navigate {
my ($modules, $settings) = @_;
my %modules = %$modules;
my %settings = %$settings;
...
}
Though you should consider just leaving them references and working on
them directly with the C<< -> >> operator.

Re: Need a little help with a sub.
If you have two hashes, you are probably better off passing by
reference, otherwise the first hash will slurp up the second hash on
the [EMAIL PROTECTED]
Something like
&Navigate(\%modules,\%settings);
sub Navigate {
my ($module_ref,$settings_ref)[EMAIL PROTECTED];

I am calling a sub with:
