Can't get Ads to Appear on site using OpenX Hosted

Setup ads using OpenX Hosted. I am using html given to me by 3rd party ad source (media rich test ad content). I can see the ads preview in the OpenX interface, so I know that the html is working properly.

Using OpenX module. If set Zone to "9" and delivery url to "d1.openx.org". I can see test ads, so I know that my site can communicate w/ OpenX.

However, I can not get the 3rd party ads to come thru to thw site.

I have setup 3 banners using html (a 728x90 and two 300x250). Each banner has an id (127343, 127344 &127626). I have setup a campaign and linked each of the banners to this parent campaign. Now I have new ids related to the linked zones. The new ids are 356565 - for the 728x90 banner and 356609 - for the 300x250 banner (only 1 id for the 2 med rectangle banners). Which ids should I input into drupal?

I am using "d1.openx.org" as the delivery url (using the hosted version of OpenX). Just realized the tremor ads are rich media. They include a video; they expand when u roll over them , play the video then retrack to original banner size. Should I use "d1.openx.org/fc.php" as the delivery url instead?
