O Wisest of the Wise, I respectfully request Your counsel in contemplating my dilemma...

I have a multi-demensional hash: %payment

I want to walk through the elements at one level of this hash:
for ( keys %{$payment}{$check_number} ) { ...

Then, I want to record in a scalar variable the number of elements at a lower level of this hash:
my $numpayments = scalar (keys %{$payment{$check_number}{$account}});

I want to walk through the values of this level of the hash:
for ( keys %{$payment{$check_number}{$account} ) { ...
(there is one more level of indexes for keys to make a list from)

While walking through the elements, I want to increment a scalar variable and have it set the value of another variable when I'm on the last element: 

my $last_payment = 0;
if ( ++$payment_count == $numpayments ) { $last_payment = 1 };

Then, while I'm in the loop somewhere, I want to take a different action if it's the last record:

if ( $last_payment == 1 ) {
    print "last record\n";
    print FH "\n";
}

    The problem is, it's not always setting the variable if I'm on the last element of the hash. I know this because it goes to the next element at the higher level of the hash, does stuff there, then goes through another element at the lower level of the hash.
