Entries can be ADDED to (or Deleted from) ANY class with one click. Simply edit the value in the 'cell' representing the class(es) to be amended. Here one entry will be added to classes 16 and 17 for the selected entrant 'Phillip Armoset'

To assist in identifying the cells a 'floater' shows the 'Class Number' of a cell below the cursor- here Class 7. (This floater can be turned off on the 'User Options' page if you don't like it).

Also, if you click on a cell, the 'Class Number' it representswill be shown top left, in the box with the '7< Currently Selected ...' text.
