Well I don't have enough time to go through all of your code. You have to do it yourself.
But I guess the main culprit is the line which begins with the comment :
//2007-06-06: freedateclubgoogle_ad_channel = "2343320155"
It should be:
//2007-06-06: freedateclub
google_ad_channel = "2343320155"

or completely remove the comment line.

The numbers in the adsense code should be quoted:
google_ad_width = 728;google_ad_height = 15;
(google_ad_width = "728";google_ad_height = "15"; )

and the lines separated for clearness and avoiding of similar problems:
google_ad_width = "728";
google_ad_height = "15";

I see you're using PHP to produce the page. You should throughly check the output before releasing it.

Success.
