[LON-CAPA-users] Referencing a part with multiple responses in a sequence

Hi All,

Hitting a new twist in our ongoing saga of collecting data inlab and passing it via sequence references to postlab for students to work with. We’re only letting them access postlabs if they have entered all of their data in the lab OR if the instructor excuses their first lab data entry (saves the instructor from having to excuse all entries).  The code for the conditional in the sequence allowing for the excused status option looks like this:

(&EXT('user.resource.resource.210.11','inlab4') eq 'excused')

This has worked great for the first three labs because the first three labs have each had only one response (response id 11) in the first part (part id 210).  In lab 4, however, we have two responses in Part 210: response id 11 and response id 12.  Excusing apparently takes place at the part level.  How should that be indicated in the conditional for the sequence?  210.11 does not work. I tried just removing the response id but simply having 210 does not work either. I thought maybe it’s analogous to not having parts in a problem and referencing it as 0, but 210.0 does not work.  Can anyone point me in the right direction here?  Thank you!
