I'll make the assumption that you mean 'part ID' and not 'part name'

Are there any error messages in /var/log/httpd/error_log?

1) curently assigned credit is assigned to 'part ID's (Meaning they
get a specfic part ID correct or incorrect
- thus by changing the part id and republishing, the old part ID is
no longer in the problem and the new part ID is not correct, which
appears to user as if they 'lost' credit, the data about the
correctness on the now missing part id is still stored just not
- the randomization of &random() is not based on 'part ID's
- the randomization of <option/radiobutton/ranks/match/image/response>
_IS_ based (partly) on 'part ID's
So if it is a <numericalresponse> in question the process of
1) change the part ID
3) regrade the scantron form for all students
Should result in every student getting a correct grade assigned.

I wasn't aware of anything not working. Off to plumb what = is screwing
