Help LS-DYNA zero thickness

I am attempting to model a honeycomb material as a solid and I continue to get an error message element ID # has a nodal thickness that is less than or equal to zero. I gather that this is an easy fix, that just requires a reassignment of properties, however I am stuck determining exactly what to do. Would some one have any guidance that may help?

Thank You

That is certainly confusing, cunfusor ,)

I dont have good advice, except that you should check your section definitions.
