When a new form is opened I need to increment the serial number. I have created a seconary data source that accesses the title field in the sharepoint library which *should* give me a list of all the existing serial number, that should return the file name which is also the serial number ie D123.xml <br /><br />So using C# managed code how can I reference this secondary data source?<br /><br />Thanks<br /><br />Lee
