Want to be able to put ads in the feed.

[rugged]

not inbetween but in the actual post at the very bottom. this should be as simple as modifying the current ad mod which i am using and love!!!
this should show up in every post made by admins,mods, and members as well as anoymous users.
this way it will incorporate the ads in the feed. $$$$
but currently i cant find a way to put the java script in and make it work, i.e; google ads.
i think thats all it would take for this to work, putting the java in the topic.
maybe i missed something or am not using the admod correctly, been trying everything i can think of.

anyone have any ideas or directions to point me in???
