How do I add the scripted workflow condition User is not Reporter?

[Sabine Van Regenmortel]

Apparently Script Runner can be used for setting up workflow conditions. How do I start? I tried by putting

Script workflow function : Simple scripted condition : Checks script:

issue.reporter != currentUser

but that doesn't seem to work. I know JIRA but Groovy scripts and Script Runner are totally new to me.

Thanks!

currentUser?.name != issue?.reporter?.name

works.
