I think the solution might be closer to:
use strict;
use warnings;
my ($name1, $name2, $name3, $name4, $name5, $name6) = ('') x 6;
print "\n $name1, $name2, $name3, $name4, $name5, $name6\n\n";
Using '' x 6 in scalar context just concats the empty string six times yielding just an empty string. So:
use strict;
use warnings;
my @names = '' x 6;
print "$names[2]\n";
__END__
Use of uninitialized value $names[2] in concatenation (.) or string at
+ ...

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).
