Breaking this frame breaker script

I've done lots of research and tried to solve this on my own, but to no avail. Supposedly this is a fairly basic method for breaking an iframe, and there are several workarounds posted. I've tried them all, and none of them work. The page still busts out of the iframe.

For example, they said two nested iframes would prevent it from busting out, (Page A iframes "victim" page, Page B iframes Page A)

Any help or advice would be greatly appreciated. Thanks in advance.
