Error when trying to do "Cut With Surface"

So I've created this funny shape and I'm trying to fill the space in between the outside skin and inside skin with the ribs.



But when I tried to do cut "with surface" to remove the excess on the outside skin and inside skin, I got this rebuild error.


TBH, I'm sure it's something in how I created the ribs that are somehow causing this error but I'm not quite sure.  Any suggestions on how to accomplish what I'm trying to accomplish the right way?  Please advise?
