Emily, in DoubleClick For Publishers parlance, the ad type would be an "out-of-page." Since that wasn't an option, I used interstitial. The ad I am trying to create is a post-it note type ad. It zooms onto the web page, remains in place for 15 seconds, then zooms out of the page. For the zooming out, the ad reduces in size to 10%, then the ad should unload completely ("close") and allow the viewer to access the content on the web page that was behind the ad. The ad I'm building zooms down to 10%, but it doesn't unload, so the viewer never regains control of the web page below where the ad is. I need to know how to unload the ad completely from the webpage after it has finished its 15-second run.
