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
