delete surfaces which are on the outside of a BREP

Hello,

I'm trying to delete surfaces which are on the outside of a box. The surfaces are split with the help of 4 planes and the Brep plane split component which seems to work just fine (found here: http://www.grasshopper3d.com/forum/topics/brep-plane-split-component) I tried to use a cull index component to delete the surfaces on the outside. But it seems that I'm doing something wrong.

Thanks a lot for you help!!

At the and it should look like this. (here i did the splitting in rhino itself)

When I control the results of the "shape in brep" manually with the list item it seems that he chooses the right surfaces. The only problem is, that I can't figure out how to delete all surfaces with with the value 2. any suggestions?
