February 16, 2019 at 14:48 #23841 Alexander BautzKeymaster When prefilling a field with vLookup there is a delay in the setting of the value (because it must run a query to get the value from the parent item). This means it will overwrite a value set in custom js when the form loads. Alexander Author Posts You must be logged in to reply to this topic.
