Thanks for that idea, John...I'll look into it.

>You could use 2 params in a view. These would become the 'between' dates in the view filter. Your table would have a 'date completed' field that would have to be set somehow once the app was completed.

>option 1 && completed
>date1 = {01/01/1900} && unless you have apps older than that
>date2 = date()
>
>option 2 && not completed
>date1 = {}
>date2 = {}

>option 3 && all
>date1 = {}
