Patrick, thanks, I will have a look at that to see if it helps.
Hilary are you guys refering to the ID field in a SharePoint List? If so I would really like to avoid this as the form will be copied and moved to another list which will replace the ID from the original list anyway so this wont work. I would really like to find a way to create this unique ID inside of Infopath so I can use that as the saved document name in SharePoint without it changing as the form gets moved around between SharePoint lists.
Thanks for any additional help
