Creating frame in IE

Hello,

I want to create a frame, in this frame there will be content loaded which must me formatted with a specific style (the reason for a iframe).

I wrote some code which works fine in firefox, but doesn't work at all in IE (I get an error). Does anybody has an idea how to fix this?

I create a jsfiddle as a demo: http://jsfiddle.net/fBe3C/

Thanks,
