switch DAX

[nanacobsbs]

I want show the regions which selected in the slicer in the card visual.
I have created the following code measure.
To Show "Global"in the card when all regions are checked in the slicer, which code should I use?

Regions =
SWITCH(TRUE(),
"America" in ALLSELECTED('Switch Regions'[Regions]),"America",
"Europe" in ALLSELECTED('Switch Regions'[Regions]), "Europe",
"Asia" in ALLSELECTED('Switch Regions'[Regions]), "Asia",
"Japan" in ALLSELECTED('Switch Regions'[Regions]), "Japan"

hi @nanacobsbs 

try to plot the card with such measure:

RegionSelection = 
IF(
    COUNTROWS(ALLSELECTED(Regions[Regions]))=COUNTROWS(ALL(Regions[Regions])),
    "All",
    CONCATENATEX(
        ALLSELECTED(Regions[Regions]),
        Regions[Regions],
        ","
    )
)

it works like this:
