Great, so the information for drop down with Company is coming from the same SharePoint list as the Contacts? And you have a repeating table that is supposed to show all the contacts for the selected company? Do you have a filter on that repeating table? Or conditional formatting? If you look in the Data Source Task Pane, and change to the secondary data source that you are using for your SharePoint connection, and drag the folder that has the data fields in it onto the form, and preview the form, do you see all the contacts from the list?
