Can't add new table field to form

Hi George, thanks for your reply. I don’t THINK that the record source for the form is a query but I may be wrong. Although if I go into the *.data file to edit the source table, in the window on the left all the tables are listed together as tables. I have made the form as a user interface in order to add data to the table. If I want to add any of the other original fields from the table I can do that fine - just not the new email address text box that I have added to the table which is confusing me. It’s like I’m doing something wrong when adding the the new text box? I have tried deleting it from the table, adding it again and saving. I’ve also tried going in to the linked table manager and refreshing it all to see if that helps to no avail. I should also add that if I open the table in normal view rather than design view, I can see the new email address field listed next to the other fields so it seems to add it to the table okay? It just won’t appear in the available fields when trying to edit the form I built
