Hello Anu, you will not be able to get any automatically generated value in autoresponder or in thank you message, such as the GUID and ID. These values are generated after both of these messages fire, not before; so you just don't have the context to do this. That being said you should have access to the other fields that are input by customer or have some default value set in these areas. Another option for the autoresponder is to create your own autoresponder by handling the BizFormItemEvents.Insert.After event that fires after the bizform is added to the database, here you will have access to the GUID and the ID.
