Scriptrunner - copy field value to another cf

JIRA TEST

hi,

My inquiry is quite simple: I would like one custom field value duplicate (copy)  to another field in the same issue whenever the first is filled/edited. 

fields are both numeric.

Probably Listener may help, could you please suggest how it should look like?

Hello,

You can find an example here:

If you write a listener then instead of issue use event.issue
