Marks return upload fails with 'Coding error detected, it must be fixed by a programmer: Unknown file type'


When uploading a marks return spreadsheet to the system, the upload fails with the above error.


The spreadsheet contains an error in the column headings 'registrationno', 'mark', 'markcode'. The two most common are:

  • An uppercase character - 'Registrationno'
  • Additional whitespace - 'registration no'. NB this will be very hard to spot if it comes after the word!
