I want to make it so that only accounts with a Type of "Client" or "Client - Group Contract" can have services. The "Type" field is a picklist, while the "Services" fields are multi-picklists. I want the multi-picklists to be blank on accounts that aren't clients.
I can do this, without errors in syntax:
AND(NOT(ISPICKVAL( Type, "Client")), NOT ISBLANK(Services_Purchased__c))
But this doesn't work:
AND(NOT(ISPICKVAL( Type, "Client", "Client - Group Contract"))), NOT ISBLANK(Services_Purchased__c, Services_Licensed__c)))
I'm getting the idea that I can't do this with ISPICKVAL, but considering the types of fields I'm working with, what else can I use?
