12. View the tblClient table in Design View, and then define a field validation rule for the Gender field in the tblClient table. Acceptable field values for the Gender field are F and M (in that order). Use the message Must be F or M to notify a user who enters an invalid Gender field value. Save the table, clicking Yes when warned about data integrity rules. Switch to Datasheet View and test the field validation rule for the Gender field, making sure any tested field values are the same as they were before your test. (Hint: You can confirm this by retyping the correct value or by pressing the Esc key.) Close the table.
