Hi Laura,
Without taking too much of a glance at your mapfile, have you tried
using the shp2img utility that comes with mapserver? Running it from a
console (we run using linux), you would type: shp2img -m [path to
mapping file]. If you have any errors in your map file, shp2img will
complain, otherwise it'll spit a bunch of gibberish to your screen for
you (actually an image printed out to console, but for now all you
should need to worry about is whether or not it can actually create an
image from your map file).
This should give you a hand in determining if the problem lies in your
map file or your webpage.
Cheers,
--Adam
