Hey,

Ok, this is something that is supposed to be easy, but I cant make it work! I have the following: 
my %a;
my $a_ref = \%a;

&resetCounters();
&add($a_ref);

print $a{'modified'} . "\n";
print $a{'removed'};

sub resetCounters {

    $a{'added'} = 0;
    $a{'removed'} = 7;
    $a{'modified'}++;

    print $a{'modified'} . "\n";
}

sub add {

    my $a_ref2 = shift;
    my %temp = %{$a_ref2};
    $temp{'modified'}++;

    foreach (keys %temp) {
        print $_ . "  " . $temp{$_} . "\n";
    }
}

And this prints:
1
removed 7
added 0
modified 2
1
7

But I want it to be:
1
removed 7
added 0
modified 2
2 <-- Notice!
7

What am I missing?

Thanks,
Ace
