I have a site that's a work in progress. It's a child theme of Twenty Twelve. For some reason the equal height columns functionality that I had working in my static html version is not working in the WordPress version of the site.

Here is a static page:

Equal height columns are working correctly.

Here is the WordPress version:
http://www.openrangeimaging.com/Test/mtn-club/?m=201305
Equal height columns not working. I have tried a bunch of hacking around in various ways to get the EHC working but no luck.

Any advice or help getting this figured out will be very much appreciated. TIA!
