Hi, I was wondering if someone could tell me how to solve my problem. I
cannot seem to draw the image, besides the ref.  image. I read the
mailing list, but that did not help. The data I'm using is from the
Census 2000 TIGER/Line Shapefiles.  I setup mapserver  3.6.3 on my
server. The demo files work fine, which to me, says the server is
configured correctly. The files that I'm using are attached. Assuming
that my ISP does not have problems the server can be accessed using this
link:
http://216.195.8.253:8000/map/massGis/

Thank you
