Oh...did you copy what you posted from there and paste it here? That's probably why it's not working for me. When I copy it from there, it works. So what I pasted in my article is this:
Code:
<iframe src="http://rcm.amazon.com/e/cm?lt1=_blank&bc1=000000&IS2=1&bg1=FFFFFF&fc1=000000&lc1=0000FF&t=aftershock04-20&o=1&p=8&l=as4&m=amazon&f=ifr&ref=ss_til&asins=B007RNWUC4" scrolling="no" marginwidth="0" marginheight="0" frameborder="0"></iframe>
and that seems to work.
