More than one banner appears on the page

[crsurf]

I currently have about 20 ads in columns appearing on certain pages of my website - www.crsurf.com. I am using zones to place the banners, and for each advertiser have checked 'only allow one ad per page' However, more than one of the advertiser's banners are appearing. Is there a change in settings that would prevent this?

I don't think there's a setting for this, but I think you do need to always use the same tag type for every zone, and also, only certain tags support the feature. See the docs for details...
