 +This part depends heavily on what you're daily_stats.php page looks like, but you should be able to take this structure and apply it to any sort of style.
 +
 +Put a script tag inside the **head** section and make it look like this. 
 +
 +<code javascript>​
 +<script type="​text/​javascript">​
 +DAILY_JAX = '​daily_stats.php';​
 +last_order_id = 0;
 +
 +$(document).ready(function() {
 +    check_for_new_order();​ // This will call the function one time, once the page has loaded
 +  });
 +
 +function check_for_new_order()
 +{
 +  $.post(DAILY_JAX,​ "​action=latest",​ function(json_latest){
 +      if(json_latest.orders_id != last_order_id){
 +          last_order_id = json_latest.orders_id;​
 +          $.post(DAILY_JAX,​ "​action=stats",​ function(json_stats){
 +          ​
 +              //
 +              // Add code to update the page here
 +              //
 +              ​
 +            }, '​json'​);​
 +      }
 +      setTimeout(function() { check_for_new_order();​ }, 15000); // This will wait x amount of time before calling itself again (in this case 15 seconds)
 +    }, '​json'​);​
 +}
 +
 +</​script>​
 +
 +</​code>​
 +
 +As you can tell most of the meaty stuff here is the [[http://​docs.jquery.com/​Post|$.post()]] function from jQuery. the first call to post uses "​action=latest"​ which should give it back the order id of the last order. If this is different from the order_id that javascript already has, it will post using "​action=stats"​. Either way, after executing it will call itself again in 15 seconds. ​
 +
 +If you used our daily_stats.php script from before, then here is a working example using that page, all AJAX-ed up. Make sure to point this file to a real copy of jquery.js.
