Using formatted numbers has hash keys is not a good idea. The data is not in $hash{00} but in $hash{0}, as 00 is interpreted as a number and not as a string.
When in doubdt about your data try either the perl debugger (run perl -d) or Data::Dumper (or Data::Denter if you have it installed):
#!/bin/perl -w
use strict;
use Data::Dumper;
my @foo = (0,1);
my %hash;
$hash{00} = "data";
$hash{"00"} = "the real one";
$hash{10} = "moredata";
print Dumper( %hash);
print '$hash{0} is ', $hash{0} , "\n";
print '$hash{00} is ', $hash{00} , "\n";
print '$hash{$foo[0] . "0"} is ', $hash{$foo[0] . "0"}, "\n";
print '$hash{$foo[1] . "0"} is ', $hash{$foo[1] . "0"}, "\n";
print '$hash{10} is ', $hash{10} , "\n";

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).
