[LON-CAPA-users] Could Not Process Request - Somewhere something went wrong

[Bob Gonzales]

Todd,

It is about 99.99% certainty that some students have not entered answers in
some parts
because one part is used only if the students want to change some of the
data that 
they have previously entered.  If they are happy with the data that they
entered then
they don't ever see one particular block.

Here's an overview of the whole set/situation.  The set is used after the
students have finished
a chemistry laboratory experiment.  They enter the experimental data they
collected 
in the lab before they leave the lab, then at some later time they answer
more questions 
that involve calculations.  I use the data that they enter before they leave
the lab to
calculate the answers to the questions that they will answer later on.  So,
the conditional
blocks make them enter the experimental data, confirm that they entered what
they intended 
and then allow them to enter the answers to the final calculations.  

Hope this helps.

Bob,

Just a shot in the dark, but . . . have all students entered something
for all parts, or are some students like to have at least one part
that is still hidden by your conditionals?  I'm wondering if that may
be the crux of the problem.  If you could check this out it might help
track down the source of the problem.
