Why does this embeded google maps item break in IE?

A coworker asked me to help try and fix this, and we are both stumpe开发者_如何学Cd. This works perfectly in firefox, chrome, and opera, yet sadly it breaks in IE. Here is the page

In Chrome, I get this error: "Unable to post message to http://googleads.g.doubleclick.net. Recipient has origin http://www.3d-4d-ultrasounds.com.", as a result of a cross-domain scripting attempt.

Could be some bung JavaScript not being picked up by IE, but having an effect?
