My guess would be that you have added a *textbox* (not a field) to a
*form* (not to a table). This symptom suggests that you have a
continuous Form or Subform, and that you've added an unbound control.
To add a new field to a table, you need to open the Table itself in
design view and add the field. You may then need to open the Form's
Recordsource property in query design view and be sure that the newly
added field is included in the form's recordsource.
