I apologize if this has been answered before. I found similar but not able to get anything to work. I am trying to hide a panel in a form: if both are true. Fn-IsMemberOfGroup() and CreatedBy or Current user is not XXX. I need to hide a panel for all members but one member of the group.
@Michel Just letting you know that the not() runtime function cannot be used in the middle of a function.
It should only be used to surround the whole function to reverse its outcome.
If a not is needed in the middle of a function the != operation will need to be used.
Your suggested function would then look like :
or(and(fn-IsMemberOfGroup('GROUP'), Created by == Current User), Current User != USERX)
