Adding GAD between ads in cats

Hey,

Does anyone know how we add google adsense in between every 5 ads for example in each category? I remember that I was able to accomplish this on the last script I had. It turned out to be pretty good for business.

Thanks.

You can use something like this in the showlisting loop:

Code:

[COLOR=#000000]{if $smarty.foreach.foo.index % 5 == 0}
     ad code
{/if}

More information please see: Smarty
[/COLOR]

Where do I add this code in showlistings.tpl?
