Im trying to validate two aspects
On Create screen, if the system downtime was indicated as yes - Radio (Yes, No), then Start of System Downtime is required to create the issue
When closing an issue
If system downtime was indicated as Yes, then resolved downtime is required to close the ticket
System downtime Radio (yes, no): issue.customfield_11009
Start of System downtime: issue.customfield_11006
Resolved downtime: issue.customfield_11007
How can i achieve this in JMWE?
