I lack a title ... apparently

Facebook is complaining that I don't have a title :

"The object at http://apps.facebook.com/254647634576238/ doesn't have a title."

I'm sure that I deserve a Title … and I know my webpage has one.

With my minimal knowldge of html, I decided to see if I could spot a title tag …. somewhere.

I found a template called header with this line :

title>{+START,IF_NON_EMPTY,{HEADER_TEXT}}{HEADER_TEXT*} &ndash; {+END}{$SITE_NAME*}</title> 

Um .. what sort of title is this. I see two title tags - and Site_Name.

Does anyone know what Facebooks problem is … or mine ?
