Thank you for reporting this! I had the same problem (about 20 clicks with no earnings). As I can see a few more people too. I thought that I included all my websites in the "Allowed Websites" so I didn't even bother to check there to see if this was the problem!
Ok, could it be cause your ads are in an Iframe? http://www.rsdln.com/adsense.html Not sure if that affects it or not, but I dont think google allows that??? I could be wrong though Or maybe your ad # is incorrect? Just throwin out different ideas
