I'm making a kickboxing archive. I would like to create a content type 'Fights'. But something isn't working.
A fight takes place between 2 fighters (content type 'Fighters'), at an event (content type 'Events'), in a venue (content type='Venues').
I need to select two fighters. I have added an entity reference of 'field_fighters'. Now I want to add another entity reference of the same field for fighter 2, but I can only refer to this field once. How can I do this?
