am using the tower layout for my adsense. The ads are stacked on top of each other with the first ad at the top then under it is the second ad and so on. This works for most of my [ages but sometimes I would like to use the horhorizont layouts with one on one page and the other on other pages without screwing everything ;f so when I log into my adsense; account what should I do to get the horhorizontalpan>; code without messing up my tower layout. If you can use both layouts then will it hurt my income in anyway?
