Google DFP Question

[robdog]

I know there are a number of members using Google DFP, and I am trying to use it. So I have a question for you experts out there. I am having a tough time getting some add spots to appear in the sidebar. One of my advertisers gave me tags to display so I added the creative as "3rd Party". A number of ad sports are working on my site minus the ones within the "ASIDE" tag.

There is 1 ad that is working, it is a flash ad that I uploaded the actual flash file. Has anyone run into this problem before?

Thanks.
