[thelist] form that sends to emailing list stores in MySQL table not working

[Bruce Gilbert]

I have set up a form where you can enter your email address and
confirm to be entered into a MySQL table database.

this part works fine, but when I try to send a sample email to the
list, nothing comes through. I was hoping somone could take a look at
my code and see if they might know what is going wrong.
// here is the form to send to the list
<form id="mailinglist" method="post" action="sendmailinglist.php">
<fieldset >
<legend>Inspired-Evolution.com Nation Mailing List</legend>
  <table class="mailinglist" summary="sends email newsletter out to
Inspired-Evolution.com Nation">
    <tr>
      <td>
          <label for="subject">Subject of email:</label> </td>
      <td> <input type="text" id="subject" name="subject"
value="<?=$subject ?>" maxlength="200" size="25" />
      </td>
    </tr>
    <tr>
      <td>
          <label for="message">Type The Message Here:</label>
          </td>
      <td> <textarea name="message" id="message" value="<?=$message ?>
cols="" rows=""></textarea>
      </td>
    </tr>
    <tr>
      <td>&nbsp; </td>
      <td align="right">
        <input class="submit" src="/images/submit.gif" alt="Submit"
type="image" name="submit" value="submit" />
      </td>
    </tr>
  </table>
</fieldset>
</form>


// code which is supposed to send to MySQL list
<?php
