Hello all,

I am having some trouble getting loncapa to not assign points if a problem
is excused.  Here is the issue:

If a problem has never been attempted by a student stores_PART_solved is
undefined and if you include it in any way in a cell calculation, it
returns "undefined value".  So I can't use it to test whether it is
'excused'.  I have tried even checking to see if it is defined using the
"defined" function, but it doesn't work either.

Any suggestions?
