Yes thanks Americo
Tried that myself on Friday last week and I to work alright!
Thanks for the confirmation.
Americo, I think, this is slightly different. I need a scroller in the filter control by customer sales top contribution, with conditional ranking based off 2014, applied to 2015. In my current set-up (due to my ignorance, or lack of knowledge), when I do the scroller on the month granularity, it ranks each customer, and if some customers in 2015 did not have any sale yet, it ranks them last in 2015.
