1) the link you sent is for the message sent page not the form page.
2) instead of pasting the code from the page in your message, it is better to compress the original php page to a zip archive and attach the zip file.
3) the confirm div is inside an message span:
<span class="emailFormError"><div class="confirm" id="confirm">Please check your forms for errors.</div></span></div>
remove the span tag.
