Portal level start

I am trying to make my first map for portal with Hammer. I have used multiple Porp_Static 's to create the elevator walls, and its "caps". The problem is I also use Prop_Static to make the elevator "body" and doors. It all looks great, and properly aligned in Hammer. But when I run the map to test; the "body" and doors just don't render in the game. The "caps" and stylized walls do, but after compiling and running, the "body" and doors are just not there(in game). Any Suggestions? I have tried moving both the "body" and the doors
