I have a class called book.pm with an attribute called 'html'. This attribute is a file which I want to write to. Book.pm uses a package called template.pm to help it write the html. I cannot seem to pass the book->html attribute to template. I get no complaints and the code runs, but I get files written in the scripts directory. Maybe a bit o' code will help clarify.

Here's an excerpt from book.pm: 
sub new {
    my ($class) = @_;

    #call the constructor of the parent class, Person.
    my $self = $class->SUPER::new();
    $self->{_name}   = undef;
    $self->{_template} = undef;
    $self->{_html}    = undef;
    bless $self, $class;
    return $self;
}
sub html{
    my ( $self, $html ) = @_;
    $self->{_html} = $html if defined($html);
    return ( $self->{_html} );
}

Later I try to toss the file to Template to build the actual page like so: 

    my $template = eval { new Template(); } or die ($@);
    $template->header($html, $header, $time);

Here's the corresponding Template.pm bit:

sub header {
    my $html     = shift;
    my $header     = shift;
    my $time    = shift;
    open (OUT,">$html") or die ("No html file: $!\n");

It's writing to text files and html files, but not the one that's passed. A sample html file is entitled: Template=HASH(0x81eb334)
Also, if I define it directly in Template then how do I access it with the other variables I pass to it. Where is it in the stack, so to speak?

I'm a bit green in the OOP department. If you've got some advice I'd be much obliged.

thanks~
