if radio button is selected show text insite text field
<p>I have to use jquery 1.3.2
I have here very simple task to check if button is selected and display a custom text inside certain textfield accordingly. I know that the problem is somewhere in the condition. Inside of condition is simple code to show custom text inside textfield with focus and blur functions</p>

<pre><code>$(document).ready(function () {
  if ($('input#edit-quote-option-flatrate-3---0').is(":checked")) {
    $('input.default').val('xxx');
    $('.default').each(function () {
      var defaultVal = ('xxx');
      $(this).focus(function () {
        if ($(this).val() == defaultVal) {
          $(this).removeClass('active').val('');
        }
      })
        .blur(function () {
        if ($(this).val() == '') {
          $(this).addClass('active').val(defaultVal);
        }
      })
        .blur().addClass('active');
    });
  }
});
</code></pre>

<p>Can you please help me debug why does not this code work with the condition? Thank you. Full code with html is here <a href="http://jsfiddle.net/NKcFs/" rel="nofollow">http://jsfiddle.net/NKcFs/</a></p>

<p>EDIT: On my page, there are more rediobuttons. I need to show text only if this certain button is selected. If visitor selects another button, the text should dissapear.</p>
