I'm cc'ing this to the Ifeffit mailing list, as others may encounter
It's not your novice-ness that's causing the problem; it's a version
issue. I wrote the ZnO example when an older version of the software
was current. Since then, "dr" became a reserved variable, and can't
be user defined. (Bruce could probably give the reason for that
change.) I fixed that, but it looks like the older version of the
tutorial is being included with the current distributions of Ifeffit
and friends. We'll fix that. In the meanwhile, though, you can just
change the variable names by hand to "delr" or something like that
(you have to change them in both the GDS screen and the path screens,
or course). Sorry about that.
Incidentally, there's a related bug in Artemis itself. If you have it
automatically come up with variables for you on a new fit, it will
name one "dr", and then can't do the fit! :(
