At the table level, for the field you want to add data validation to:
Validation Rule: = 1 Or 2 Or 3
Validation Text: Please enter a valid zone number
Required: Yes or No
If you enter 4 in this field, you get the message "Please enter a valid zone number"
If you enter 1, for example, you get no error message and move on.
If you want them to have to enter a zone number, make the field required.
Does this help?
