Sorry for the double-post, but here is an example of what I'm talking about. This is Mr. Wiggle's Alchemy script I'm using. I've copied/pasted this verbatim from my game. I've yet to make any changes to it--it should be the default. It doesn't crash when I call the script, but the text is invisible and you can't read anything.

# the Blue print id refers to the location of the recipe in the
# ALCHEMY_RECIPES array, also remember that it starts counting at 0, this
# means that 1=0, 2=1, and so on.
