You need to
use Data::Dumper;
in order for the Dumper function to be accessible in your code; then
print Dumper $sheet;
will actually print something. See Data::Dumper. (I tend to like Data::Dump a bit better.)
... even though I have:
$sheet = $book->[$sheet_index] or next;
this does not seem to be doing the trick.
But my point remains the same: in order for a statement like
$name = $sheet{"${_}28"};
to work, a hash named %sheet must exist somewhere in your code (somewhere in scope, that is). I.e., there must be a statement something like
my %sheet = ( ... );
somewhere. Do you say that such a statement exists?
Update: The other point to make is that if the %sheet hash actually does exist, the expressions $sheet{"F28"} and $sheet->{"F28"} access two completely different hashes!

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).
