Custom Post Type Support

I'm trying to get the Product posts to support the Genesis Simple Sidebars plugin. From everything I've read here, this is the snippet of code that I would need to use to get it to work, but it does not load them.


function add_custom_post_support(){

The odd thing is that if I were to change "genesis-simple-sidebars" to something that's a theme feature, or a wordpress feature it works just fine.

Any thoughts on this?
