I'm using Adaptivist Scriptrunner. I need to clear both values within a cascading custom field when an issue transitions into IN PROGRESS. I can't figure out how to do this, and I can't see any examples on the Adaptivist site.
Can anyone give me a step by step guide? The simpler the better, as this is something I have very little experience of. Actual code where I can just substitute field names would be ideal!
Edit: No "you can do it using this paid for app" answers please.
