[LON-CAPA-users] using &submission() between problems

[Stuart Raeburn]

Bob,

The syntax is described in the LON-CAPA Script Functions help item:
e.g.,
http://loncapa.chem.binghamton.edu/adm/help/Problem_LON-CAPA_Functions.hlp

To access a student's submissions in a different problem you need to  
supply a sixth argument -- a maplias, and the call is:

&submission($partid,$responseid,$version,$encode,$cleanupnum,$mapalias);

In the case of a published sequence, where you have authoring or  
co-authoring rights, you can set a mapalias for a particular resource  
in the sequence using the Advanced Editor in Authoring Space (prior to  
publication).

If there is no mapalias set you can use the (much longer) unique  
identifier of the resource instance (known as the "symb"). If you are  
using a folder added via the Course Editor rather than a published  
sequence, there is currently no mechanism to set a mapalias for a  
particular resource instance in the folder (which is actually still a  
sequence internally in LON-CAPA), so you will have to use the "symb".

You can display a list of "symb"s in a course using:
Course Editor > Content Utilities >  List Resource Identifiers
(the "symb"s are in the "Identifier" column).
