I've found another way to my problem. I just put all of my banner's codes into one banner, called it "All Banners" and it did it. You can see it here: www.api.kh.ua/zen I can't see the statistics of each of the banner from the Admin section, though. My way is probably not the right way of solving the problem, but I can't think of anything else. The only other way would be to use the sidebox_banners_all.
