Creating an Event calendar using PHP and jQuery

Creating an Event calendar using PHP and jQuery

Hello all,
 
JQuery newbie here.  I think the problem i've got may be blindingly simple really, but it's got me stumped.
 
i've downloaded an events calendar from here http://iambari.com/2009/05/05/create-an-event-calendar-using-php-and-jquery/ and its ideal for my purposes. I have everything working fine.  Apart from the current month does not display as the title, I just get the calendar, with all the days of the week falling in the right place but nothing to tell you what month it is.
 
The demo clearly shows the current month as a bold title, but i've been all through the code and can't see if its a Jquery, Javascript, php or html problem.
 
If anybody cold take a look and give me a suggestion, it would save me hours of head scratching.
 
Thanks
