Ads Not Showing

So after being a DP member for hundreds of years (of internet time), I finally am about to set up my coop account.

I have:
created ad_network_137.php, ad_network_ads_137.txt (with permission 666). My page has a footer file which is included in the html by:

<!--#include virtual="footer.html"-->

Code (markup):

and it works fine. So, I went into footer.html and put:

<!--#include virtual="/ad_network_137.php" -->
<!--#include virtual="/ad_network_137.php"-->
<!--#include virtual="ad_network_137.php" -->

Code (markup):

(I tried all 3 variants one at a time)

My ads don't show. I think it is do with the .htaccess enabling of the php. But, I do not have access to the .htaccess (as I manage only the subdomain and am not allowed to change .htaccess). Is that what is causing the ads to not show? Is there anyway I can check if my site is already set for php?

Thanks

Yes it is, as seen at:

That did the trick. Ads are now showing. If I can just know how to make them appear on the same-line as opposed to one-below-the-other, I am all set. Thanks.
