I can't get the value of an interaction selection

[Kimber]

I have interactions turned on, and selecting a value in a matrix filters the other charts on my page. I want the selected value to be shown in a card, but I can't make it work. In the image below, the card below should say "Two or More" because that's the value selected on my matrix. Instead, it says "Not filtered." The measure I'm using on the card is this:

Selection: Ethnicity = 
    IF(
        ISFILTERED(
            PowerBIByTheNumbers_Current[Ethnicity]
       )  
    ,
    SELECTEDVALUE(PowerBIByTheNumbers_Current[Ethnicity]),
    "Not filtered"
    ) 

Can someone please tell me what I'm doing wrong?

@Kimber Try HASONEVALUE instead of ISFILTERED

@Greg_Deckler  Thanks for your help! Unfortunately, I get the same result. The expression is not picking up the fact that I've made a selection. Is there a setting I need to check?

I figured it out! The default of my card was "no interaction." Once I changed it to filter, it worked. Thank you!
