send to all......

If I send an emailreport to my students mail sends them to all students in the column, also to students who have no grade (didn't anticpade in the "Toets" (test).....could it be that the source of this is that I coloured the column?

Enable the 'Skip empty cells' option and it won't send the e-mail if the cell is empty.

Any idea where to find it?
