Once you have one or more zones, you can link the zones to a campaign. To do so, click thetab when viewing the campaign. Check the box beside the zones you want to link. At this point the checked zones are linked to the campaign.
If you are displaying the linked zones on your web site, then any banners belonging to the campaign will be candidates for display in the zone.
To unlink a zone from a campaign, uncheck the zone from the list of zones in.
