Hello,,
I'm trying to achieve the below simple requirements since long time but I couldn't 
let me know if you have any solution
I have two fields group field "Assigned Group" and multi users field "Group Members".
I need to create an automation role triggered when "Assigned Group" is being filled with a group name and the action will be to return the group members in the filed "Group Members". I tried multiple smart values but it is not returning any result.

can i achieve this requirements through automation or if you have any solution using script runner ?
