This is /res/ohiou/OUp200lib/sfChpt13/sf1302b.problem that is part of
the msu/mmp/phy231c.sequence course.

How are the instructors to know which parts in a course are assigned 
part 0, without going through each single item of a course?

When I found out I set answer date, due date, and open date for part 14
and 16, but that still produced the error in the dartgun entry of the
spreadsheet. The error, by the way, reads:

bad parameter name : parameter_0_duedate 

(I don'y know how to delete the due date for a single problem. -The due
date for this problem weas originally set at the Map- or course- level)
