I attempted to perform this operation using a Microsoft SQL Database connection and I'm able to setup the connection but, when I attempt to publish the form I receive an error that says, "Additional Data Connections not supported." After receiving this error I again tried using an existing list in SharePoint to populate the dropdown and I still receive the same error message. I'm new to ECT custom forms and would appreciate any advice.
