stary text above head tag on order confirm page

I'm trying to track down how one page might have a couple of "n"s appear above the head tag, which is messing up styles in IE.

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml" dir="ltr" lang="en"> <head> <title>Step 3 of 3 - Order Confirmation : Lake Forest Symphony Orchestra :: Shopping</title> <meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1" /> <meta name="keywords" content="Subscriptions Merchandise Individual Concert Tickets Donations Gift Certificates concert tickets Step 3 of 3 - Order Confirmation" />

Any ideas as to the source of the two "n" s above the DOCTYPE tag? What files might I look at?

This is only on:
https://id3420.securedata.net/lakeforestsymphony/shop/index.php?main_page=checkout_confirmation&zenid=

and not on other secure (or unsecure) pages.

I fixed the STRAY text problem (sorry about the typo in the subject line!):

includes\languages\english\checkout_confirmation.php (and the one in my own template) both ended up with "n" in front of the <?php tag.

(It's a problem with the way I FTP upload in Dreamweaver, answering questions about dependent files before they are asked!)

With these deleted, the page is fixed.

Whew!

FTP upload in Dreamweaver,

Suggestion? get a good FTP program and never use Dreamweaver (or any WYSIWYG editor's built-in FTP) when working with php files.
