Blog Modifications and Other Extreme Suckage

I've spent my entire day making template changes to my blog using a dummy template. When it came time to install Haloscan in this dummy template, all went well until I tried to upload the new template back to Blogger after Haloscan did their magic.

Your template could not be parsed as it is not well-formed. Please make sure all XML elements are closed properly.
XML error message: The element type "p" must be terminated by the matching end-tag "

Well, fuckers. I don't suppose you could enlighten me as to WHERE this inpropriety occurs, since I have like a gazillion "p" element types.

This is doing nothing to enhance my love of Blogger. Let me assure you.
