jQuery Countdown timer

jQuery Countdown timer

Hi,

I'm trying to use the countdown timer from this tutorial on my website.  I got it to work, but I can't get it going on multiple clocks with unique end dates.  This is what I've tried and it only works on the last selector.

  1.  <script>
            $(document).ready(function(){
                $('#countdown').countdown({
                    date: "20 July 2013 12:00:00",
                    format: "on"
                }),
               
                $('#countdown2').countdown({
                    date: "21 July 2013 12:00:00",
                    format: "on"
                })
            });
        </script>













 I know there must be some method I'm not aware of for running them simultaneously.  Can anyone help me get these clocks going at the same time with different dates?  I don't want to use another plugin because they don't allow me the same control over the html/css.  Thanks,

Brendan
