Hi,
I´m trying to append X (object) to an objects Custom Field in Assets.
The automation works well when the field is empty.
Then I add the Asset Field Value Location to the Asset Field Value Previous Location, like below:

However, when the field is already containing a value, I would like to keep the previous value and append a value to the custom field. Like below:

In general terms:
IF A are empty
A = X
Else
A = A + X
end
This is however not working well on how Jira is updating objects.
Can anyone provide guidance here?
Thanks,
Johannes Nyberg
