In Confiforms, I have a checkbox group mycbgroup with checkboxes cb1, cb2, cb3, cb4, cb5.
I am trying to make some of them work as a sub-group ... so (e.g.) if user checks/unchecks cb1, then this checks/unchecks cb3, and vice-versa.
I almost have this working using Field Definition Rules, as I know how to create a rule that turns specific checkboxes on ... by using a Set Value action as follows:
mycbgroup=[entry.mycbgroup.asList],cb1,cb3
My question, how do I write a rule that turns specific checkboxes off?
