I've been away from Markup Language for several years so I'm worse than rusty. I'm trying to make a form that will come to my email address when sent. I can get it up on the website, but it gives me a 404. I'm doing something wrong, but not sure what it is. It may be the PHP at the top. I'm including the markup. Any assistence appreciated. Thanks.
<form name="htmlform" method="post" action="html_form_send.php">
<table width="475px">
</tr>
<tr>
<td valign="top">
<label for="first_name">First Name *</label>
</td>
<td valign="top">
<input type="text" name="first_name" maxlength="50" size="50">
</td>
</tr>
<tr>
<td valign="top"">
<label for="last_name">Last Name *</label>
</td>
<td valign="top">
<input type="text" name="last_name" maxlength="50" size="50">
</td>
</tr>
<tr>
<td valign="top">
<label for="email">Email Address *</label>
</td>
<td valign="top">
<input type="text" name="email" maxlength="80" size="50">
</td>
</tr>
<tr>
<td valign="top">
<label for="telephone">Telephone Number</label>

<td valign="top">
<input type="text" name="telephone" maxlength="30" size="50">
