I used this command: GetAttachmentAttribute/xpath = /my:myFields/my:Sect_NotaryDetails/my:ATTACH_Notary /attr = Name
But, got this error: "GetAttachmentAttribute/xpath" does not point to a valid location path of a field or group.
My rule on the attachment field is Set a field's value - None - Rule runs when field changes. I pulled the x-path from "Copy XPath" (/my:myFields/my:Sect_NotaryDetails/my:ATTACH_Notary)
