AD's not showing? vBulletin 4

So i clicked new ad in my admin section, click the area i'd like the ad to be, enter my code, save it and nothing shows up on my forums? Could somebody explain how this works?

I should also mention I have my own skin and not the default vBulletin skin.

 

Link to site would be helpful. If it is Adsense, odds are it will take awhile to replicate to your site.

 

I figured out what to do, I ended up using the edit template feature.

 

You shouldn't be editing templates if you're using vBulletin 4. There is a built-in advertising manager that works just fine.

 

I never use the built in ads because I place them where vB doesn't give me full control. I don't think I've ever used the ad manager, lol.
