Hi Christian
I noticed that this when answering this question, the computed answers are no longer being used and it keeps 0 as the correct response.
Best wishes,
Josh

This is a strange place to have a thread, but if you reading this, Mike, you may want to take a look at this question:

Hello Christian,
I really enjoy the possibility of using data from an external file (e.g. csv or Excel) in Numbas: I was wondering whether it would be possible to randomise between differerent files. I have a group of about 300 students and want to let them run a regression and let them answer some questions about the regression results. Is it possible to randomise between for example 50 different csv files (in order to avoid copy/paste behaviour among students)?
Kind regards,
Mike

For each combination of answer and choice, specify the number of marks to add or subtract when the student picks it.
For each combination of answer and choice, write 1 if the student should tick it, or 0 if they should leave it unticked.

Test that the marking algorithm works
Check that the marking algorithm works with different sets of variables and student answers using the interface below.
Create unit tests to save expected results and to document how the algorithm should work.
There's an error which means the marking algorithm can't run:
Question variables
These variables are available within the marking algorithm.
| Name | Value | |

Marking parameters
These values are available as extra variables in the marking algorithm.

This test is not currently producing the expected result. Fix the marking algorithm to produce the expected results detailed below or, if this test is out of date, update the test to accept the current values.
One or more notes in this test are no longer defined. If these notes are no longer needed, you should delete this test.

When you need to change the way this part works beyond the available options, you can write JavaScript code to be executed at the times described below.
To account for errors made by the student in earlier calculations, replace question variables with answers to earlier parts.
In order to create a variable replacement, you must define at least one variable and one other part.
| Variable | Answer to use | Must be answered? | |
|---|---|---|---|
The variable replacements you've chosen will cause the following variables to be regenerated each time the student submits an answer to this part:
These variables have some random elements, which means they're not guaranteed to have the same value each time the student submits an answer. You should define new variables to store the random elements, so that they remain the same each time this part is marked.
This part can't be reached by the student.
Add a "next part" reference to this part from another part.
None of the parts which can lead to this part are reachable either.
