Help with % in stacked column chart.

I've found a very simple way around this issue.

I created a 2 columns in the table to reference the series and a Disctinctcount of customers, based on the parameters that are on the slicers. As I get the same number in mutiple row I just used a MIN tu get 1 number in particular.

The Problem now is that althoughis working fine for individual countries in a slicer, as soon as I choose 2 or more it does de distinctcount correctly, but it doesn't sum up the reference period.

I modified the formula not to use the min, but to sum up the references for those countries using a Rank so I don't repeate any unwated data. This doesn't work. It still only takes the numbers of 1 country instead of the sum of all the selected.
