Hi @NofalBC
Just delete that activity and reassign the activity, indicate the element and then pass the variable to the Selectors and check the Override default value option when passing variable to selectors. It will work now.
After passing the variable in the selector, then change the variable scope it will show the error. we have to do the above process.
Then it will works. It already works for me!!
Check the below thread for your reference.
Hope it helps!!
