dynamic div height detection and matching

dynamic div height detection and matching

Hi Folks,
Hope you can help me out here.

I have 2 divs in a wrapper div. left inner div floated left and the right inner div floated right.

The left hand inner div contains a number of suckerfish slide down divs which contain dynamic content and ultimately slide down the height of the left hand div when one of them are expanded.

My problem is that I want the right inner column [ which just contains text ] to change height to match the left div when the dynamic content in the left div is clicked on and slides down.

I have looked are binding a resize and adding a watch but nothing seems to work cross browser - I have got to get it running in IE7/IE8 & FF.

Any ideas?
