Is there a logic error in there?

if ( exists $list{$location} ) {
    my $value = $list{$location};
    $value++;
    $list{$location} = $value;

# if  $list{$location} doesn't exist then it always eq '' ?
# } elsif ( $list{$location} eq "" ) {

# test $location instead?
} elsif ( $location eq "" ) {

    if ( exists $list{Unknown} ) {
        my $value = $list{Unknown};
        $value++;
        $list{Unknown} = $value;
    } else {
        $list{Unknown} = "1";
    }
} else {
    $list{$location} = "1";
}
