If you name another form in the Validation Form field, the operator can temporarily switch to that form, find the desired code, and switch back to the current data entry form. The form named in the Validation Form field is displayed on the screen. The operator can perform queries using that form to find the desired code. The operator can also add or update records using the validation form if those operations are allowed. The code that was displayed on the validation form is copied back to the field being validated on the current form.
Form then continues data entry with the next field on the form.
You must create the validation form itself as another form in the same formfile. It should have the Repeating Form field set to yes , and possibly the Unique Records field set to yes , and all other form description fields should be no . The Next Form Name field should be the same as the name of the validation form. As an example, we will use a validation form with the subscriber field in the Subscriptions form. We must add a second data entry form, which we call valsubscriber .
