When I copy a customized button action set from one of my screens to another (action to enter something in the "Status" field when clicked), the newly copied button action said to enter it into one of the "bill address" fields instead.
Hey Maureen,
I can try to replicate it on my end, I will need some more information on which screens you are working with.
Also wanted to add if it was just that one field it was updating, Shared Result might be a better route to try.
