Open the Relationships window, and check how the tables are related. Open the table named Tasks in Design view. Create a validation rule for the table so that you can't enter a value for DueDate that's earlier than the value of StartDate (although the dates can be the same). Enter a message in the Validation Text property that will be displayed if a user enters data that violates the validation rule. Test the validation rule by entering dates in these two fields.
