With -w enabled you can't use params like that without getting uninitialized value warnings when the params aren't defined. Also $q->param{'Address'} shouldn't have curly braces but parentheses: $q->param('Address').

This version shows a way to properly initialize the variables whether the params exist or not.

#!/usr/local/bin/perl -w

use strict;
use CGI;
my $q = CGI::new();

my $name = $q->param('Name')    || '';
my $addy = $q->param('Address') || '';

print $q->header;
print <<HTML;
  <form>
  Name: <input type="text" name="Name" value="$name">
  Address: <input type="text" name="Address" value="$addy">
  <input type="submit" value="Refresh">
  </form>

Are you posting in the right place? Check out Where do I post X? to know for sure.
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).
Want more info? How to link or How to display code and escape characters are good places to start.
