Hello!

I'm having trouble creating this formula for a validation rule. This is what I'm trying to accomplish, If the Engagement plan template's default assignee is blank, then I would like for the contact's "pathway coach" to be assigned. No errors were found, but the engagement plan tasks are assigned to me (the contact owner) despite the default assignee being blank

AND(ISPICKVAL( npsp__Engagement_Plan_Template__r.npsp__Default_Assignee__c ,
"--None--"),
ISNULL( npsp__Assigned_To__r.Contact.Pathway_Coach__c ))
