I have a form that is to be filled out on Sharepoint. When the form is finished, the inspectors are to select their name from a dropdown list and then a text box will populate with their electronic signature. I am using Sharepoint 2007 and Infopath 2010 and creating a 2007 form. I have tested the form without the data connection and it opens fine, but as soon as I add a connection, it gives me an error "An error occurred accessing a data source." I have done everything I know to do and it doesn't work. I've converted the connection and tested and not converted the connection and tested it. Can anyone give me the steps to create my listbox and populate it with the data from my SQL database so it will work on Sharepoint?
