Countdown timer alert popup

I'm getting this alert popping on any page with an AJAX call on it (see attached)

I'm running D6.13 and UberCart 2.x. I installed the Countdown Timer 6.x-2.x-dev snapshot, updated the configuration file and SHIFT + reloaded several times but to no avail. The alert pops up - followed by an alert with the timer variables in it. It's only a dev store but you can take a look here - the countdown is near the bottom of the left column:

I also noticed the timer is only working in Firefox. Safari 3.2 and IE 8 do not display the countdown. Getting this JS error from IE:

Message: Expected identifier
Line: 50
Char: 12
Code: 0
URI: http://storepreview.aegadvancedmedia.com/sites/default/files/countdownti...

Here is the code I am using in the timer block:

<p><span class="countdowntimer"> <span style="display: none;" class="datetime">2010-02-17T09:30:00-08:00</span> <span style="display: none;" class="format_txt">%days% days, %hours% hours, %mins% mins, %secs% secs</span> </span> <span style="color: rgb(0, 0, 255);"><strong>until the 2010 Amgen Tour of California</strong></span></p>

cheers
