html / php评论框没有发送电子邮件

Question

I have a simple html form that sends a request to a php file which in turn should send an email. The request to the php file works and the confirmation text is displayed but no email is sent.

I'm really stuck and can't work out why the email is not being sent. Is their any problems with my php?

HTML

<form name="htmlform" method="post" action="html_form_send.php">
    <table width="450px">
     </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="30">
     </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="30">
       </td>
       </tr>
        <tr>
        <td valign="top">
             <label for="email">Email Address *</label>
        </td>
        <td valign="top">

         </tr>
         <tr>

          </tr>
         <tr>
          <td valign="top">
                <label for="comments">Product wanted for import *</label>
          </td>
