Portals Game

hi, I followed/used the portal sample blend that was somewhere on this site. It actually worked well. But when implemented into my game the textures of the portals are upside down, and for some reason I can’t go through the portal I just hit it. I have named everything the same and used the exact same script. Please help. This all occurs in the scene level1. Here is the blend. It is too big for the forum sorry
