If you just use this script above and change Radio1, Radio2 etc for the names you want random you will everytime get a random name

Change result=BLApp.apiPut(“ RadioDay etc etc into result=BLApp.apiPut(“ Name etc etc  
Make a better logic variabel called Name1 and everytime you run this script you will get random name
