I have written a droplet that uses a shell script (from macosxhints)

If I remove the "try" I get an applescript error that appears to be
the names of duplicate files, so it looks like the "do shell script"
is working (it also works in the Terminal) but for some reason I
can't set the_results to the text returned from the shell script?
"Works" is using the term a bit loosely. If "do shell script" is
throwing an error, then that means the command is exiting with a non-
zero status, which usually means that it thinks something is wrong.
The fact that the output you want is showing up as the error message
is sort of accidental -- if the command exits with a non-zero status,
then whatever came out on stderr becomes the error message -- unless
there wasn't anything, in which case it uses the contents of stdout.
This can be highly misleading. You need to figure out what's going on
in dupecheck. You should also have a look at TN2065 <http://developer.apple.com/technotes/tn2002/tn2065.html

P.S.: If you can assume you're running on Tiger, you can use "path to
resource" to locate dupecheck instead of "path to me" and then
building the rest yourself.
