Click tracker for chitika (like the Adsense one)

Hi all,

I hope I'm at the right place here,

I'm using a small extra code to log all the click (from IE users) on my Adsense ads

<script type="text/javascript"><!--

function hit()	{ 
		window.focus(); 
		if (window.status)	{ 
					img = new Image(); 
					img.src = 'log.php?ref=' + escape(document.location) + '&link=' + escape(window.status); 
					}; 
		}; 
document.getElementById("google_ads_frame").onfocus = hit; 

//--></script>

Code (markup):

Once a user clicks on an Adsense ad, the code will send the data to log.php.
Log.php does the rest that I want it to do...

Anyway..

I've had a look at the 'http://scripts.chitika.net/eminimalls/mm.js' code, and it does look like they also use the getElementById and onfocus, so theoreticly the code should work (with some small changes).. (like Adsense)

I've been trying to change the above code for some time now, but whatever I try I keep getting an 'Error: 'document.getElementById(...)' is null or not an object'

Are there any good coders here who might be able to get this to work with the chitika's ads?

Thank you....

 

I don't get what the use of this is?

 

To see who (as IP) and on what (as link to the advertiser) add the user clicked on.
