Hi, on a side note, you don't need to pass to Data::Dumper a reference to the structure you are dumping, if that structure is already a reference.
my %hash = ( foo => 'bar' );
my $href = { baz => 'qux' };
print " hash: ", Dumper( \%hash ), "\n";
print "hashref: ", Dumper( $href ), "\n";
Hope this helps!
The way forward always starts with a minimal test.

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).
