In Bromcom, the setting you likely want is under Config > Attendance > Attendance Codes. The attendance-code guide confirms that you can select a code and edit its display settings, including the mark used for attendance entries.

What to do

  1. Go to Config > Attendance > Attendance Codes.
  1. Find the code you want to change and click Edit.
  1. Check the mark/label settings and the display colour, then Save the change.

If the “question mark” means the attendance mark

The Bromcom docs show that marks are managed as attendance codes, and only specific marks can be created from that page. If your register is showing the wrong symbol, the most likely fix is to edit the relevant attendance code rather than changing a general keyboard setting.

Common extra check

Bromcom’s FAQ also notes that the attendance code must be ticked to include in teacher registers in the new academic year settings. If the mark still does not behave as expected after editing it, that checkbox is worth checking too.

One-line version

Change it in Attendance Codes , edit the relevant code, and make sure it is included in teacher registers.

If you want, I can turn this into a very short step-by-step for staff or students.
