hamiltonptmt on "HTML help with contact form"

I'm using the following HTML for a contact form:

<form action="html_form_send.php" method="post" name="htmlform">
<table width="450px">
<tbody>
<tr>
<td valign="top"><label for="first_name">First Name *</label></td>
<td valign="top"><input maxlength="50" name="first_name" size="30" type="text" /></td>
</tr>
<tr>
<td valign="top"><label for="last_name">Last Name *</label></td>
<td valign="top"><input maxlength="50" name="last_name" size="30" type="text" /></td>
</tr>
<tr>
<td valign="top"><label for="email">Email Address </label></td>
<td valign="top"><input maxlength="80" name="email" size="30" type="text" /></td>
</tr>
<tr>
<td valign="top"><label for="telephone">Telephone Number *</label></td>
<td valign="top"><input maxlength="30" name="telephone" size="30" type="text" /></td>
</tr>
<tr>
<td valign="top"><label for="comments">Comments *</label></td>
<td valign="top"><textarea cols="25" maxlength="1000" name="comments" rows="6"></textarea></td>
</tr>
<tr>
<td style="text-align: center;" colspan="2"><input type="submit" value="Send E-Mail" action="mailto:robyn.t@hamiltonpt.com"/></td>
</tr>
</tbody>
</table>
</form>

For the life of me... I cannot get the "Send E-Mail" button to link to send an email. I know that it is <mailto:"email address"> but it won't work no matter where i put it. Anyone able to help with this? Our current form from theme 2012 won't transfer over very well.

Thanks in advance!
