Mark,
Show all parts works. Thanks again.
Also the modified problem now appears to accept two answers, for two =
different assumed values of the resistivity of copper. I assume I =
should thank hk for this.

Perhaps it is using the value at 25 deg C rather than 20. The numerical =
tolerance for the problem appears to be set at 1%, so my students will =
be marked wrong unless they know the value the problem is using. So I =
go to the page to modify parameter settings and set the tolerance to 5% =
for this problem in my course. But then I check the range of allowed =
answers for some students and it still looks like 1%. Why does my =
setting of the tolerance not override the default setting of the =
problem? What do I need to do to fix it.
