Delivery Options - URL not working

[AdGuy]

I'm new to Revive, using the Hosted edition. I've created a campaign, banners and identified the Zone.. I set up a Delivery Rule Set and included a "is equal to" URL. I then used the iFrame option and placed the code in my WordPress site on the page matching the URL. However the banners never show up. I have gotten a regular banner placement to work but I can't get the banners to show up when using the Delivery Rules. Can you help...

Here is the iFrame code if that helps.
