Adsense Not Showing Up

[RcHelp]

Hello all. On my forum, I have the advertising set to show a high amount of ads just to pay for the site. But, the header ad that the forum is supposed to put in there will not show up for some reason. I had to modify the nav template to ad the code directly for an ad.

I want to fix this issue cause I'm thinking about doing a "paid" membership, and one of the perks is to get rid of the ads. Well, I can't do that if it's in the code it's self. But I can do it through the AdminCP>Advertisement tab.

Someone help me out here. I'm sure this has to be a simple code error that I am just not finding. YOu can click on the link in my sig, and click on the forum tab to see the way I have it now. You do not have to make an account.

As always, thanks in advance!
