Add attachment through PHPMailer

Question

I have this following piece of code of PHPMailer. The problem is, that the file uploads to the server successfully but the attachment is not sent in the mail. The attachment code seems right to the best of my knowledge. Please review the code and let me know where have I gone wrong.

Form

<form name="contactform" method="post" action="send1.php" enctype="multipart/form-data">
<table width="100%" border="0">
<tr>
 <td id="ta">
 <label for="title">Title *</label>
 </td>
 <td id="ta">
 <select name="title">
 <option value="0">Title</option>
 <option value="1">Mr.</option>
 <option value="2">Ms.</option>
 <option value="3">Mrs.</option>

EDIT The mail sends successfully with all the details too. Just that the attachment won't send.

EDIT 2: SOLVED Changed $mail->MsgHTML to $mail->Body and it worked!
