I have a validation/logic question.
I have a form that gives multiple options and checkboxes to select them:
Now, the issue is that a person can enter multiple events which could be
Football AND Tennis BUT NOT Golf as it would clash with the Tennis!
Badminton AND golf BUT NOT Athletics,
some organisers can put Tennis AND golf on at the same day and allow entry to both.
So I need a reliable way for an organiser to be able to specify which sports are allowed within a multiple entry array.
