Need help with height="100%"

Hi.

I have a blog post on Blogger that is coded like this:

  Code:

<div>
<a href="http://pimpjuice1337.blogspot.com/2010/08/pimpjuice1337-is-not-dead.html">Home</a> → <a href="http://pimpjuice1337.blogspot.com/2009/01/error-embedded-data-could-not-be.html">Noban's</a></div>
<div>
_</div>
<div>
<iframe height="100%" width="100%" src="http://nobans.conforums.com/" frameborder="0">Noban's</iframe></div>


However, as you might see on the link, the iframe doesn't expand in height and just stays about 250 px or so, so that there's a second scroll bar for the iframe. How do I make the iframe automatically extend to the full height of the embedded object?

I've checked TONS of articles claiming to be the solution to this problem, but nothing I'm trying is working. Please help, thanks.
