Question on court editing

I extracted the .fsh files to modify a few courts, but I get an error when I try to get the new files into a .fsh file when I drag the index of the .fsh tool, I get this wierd script. What is the proper way to import new court graphics into the game? If somebody knows can they please give me an idea?

If you go to the EAGE section of the forum, there SEEM to be some posts by some techs about court graphics . I THINK there is some kind of problem in dealing with EA's new programing formats. But its all stuff way, way, way over my head.
I haven't tried messing with courts yet. but when I was just goofin around with the game after I first got it, I noticed eage showed the court graphics in all f'ed up colors. Sorry, thats all i know (or think i know.)
