You have to be very picky with your quotes.  If any part of any line in your
script would be something you would type in at the console (in Grads) to do
outside of a script, it needs to be in quotes.  That means any define,
display, or set plotting environment commands.  You need to change the line

uwnd = uwnd - uwnd(i-1)    to

'uwnd = uwnd - uwnd(t-'i')'     ("i" needs to be outside the quotes as you
see it.  That way the Grads script will sub in an integer value for "i" and
you'll get your t-1, t-2, etc)
