Several ways to do this.
I did a window_sum of [Apples] and another for [Bunny]. You can do the same for [Fuzzy].
For the sake of demonstration, I just dumped them into the title of the sheet.
That gets you the counts, but I'm not sure that's what you really want.
I also added a parameter to let the user select one of the values. Then I just filtered the expanded sheet using the same type of calc you used to count APPLEs. User selects a value, and expanded sheet changes accordingly.
