HTML email submit form

Having a problem with an email form. When clicking submit doesn't recognize page. Am I missing something really obvious? I've replaced 'your email address' for a valid email address in VALUE.

Here is the code:

<form method="post" action="http://www.ftp://www.users.greenbee.net//cgi-bin/FormMail.pl" name="MyForm">

<input type="hidden" name="recipient" value="YOUR EMAIL ADDRESS" />
<input type="hidden" name="sort" value="order:FirstName,Surname,emailaddress,Comments" />

<center>

<table border="0" width="64%" bgcolor="#c0c0c0">
<tr>
  <td width="41%" align="center"><strong>First Name</strong></td>
  <td width="59%" align="center"><input type="text" name="FirstName" size="24" /></td>
</tr>
<tr>
  <td width="41%" align="center"><strong>Surname</strong></td>
  <td width="59%" align="center"><input type="text" name="Surname" size="24" /></td>
</tr>
<tr>
  <td width="41%" align="center"><strong>E-mail Address</strong></td>
  <td width="59%" align="center"><input type="text" name="emailaddress" size="24" /></td>
</tr>
<tr>
  <td width="41%" align="center"><strong>Comments on my webpage</strong></td>
  <td width="59%" align="center"><textarea rows="3" cols="24" name="Comments"></textarea></td>
</tr>
<tr>
  <td width="41%" align="center"><input type="submit" value="Send Form" name="SendForm" /></td>
  <td width="59%" align="center"><input type="reset" value="Clear Form" name="ClearForm" /></td>
</tr>
</table>

</center>

</form>
