[IxDA Discuss] select exact number widget?

[Mark Roudebush]

Victor,

I like the metaphor of the apples.
Perhaps showing two open fields that are filled when selecting an  
option from a list. As the user selects a third choice one of their  
already filled in options is replaced. This would easily show there  
are two available options.
