1 problem;)

hello, I started today with the macro page …
My intention is to only sound one zone at a time (I have three)
So I created a string variable and I assigned the different previewzone parameters to each slot, then I created 3 radio buttons (so that only one was on) and assigned them all to the string variable that I had created and I thought that was all, but it doesn’t work ,any advice?
I attach the macro
Mute Zones.zip (3.22 KB)

solved, I leave it here in case anyone wants it
