Abstract: Systems, apparatuses, and methods for verifying or validating the use of a combination of data entry fields or regions that are part of a form, template, webpage, or other display capable of receiving data entered by a user. The invention determines which of the fields or regions contain data that the user has entered. This represents a specific “combination” of data entry fields in which a user has entered data. The invention then determines whether the user's combination of data entry fields is a valid or acceptable one. If the user's combination of data entry fields represents a combination that was previously determined to be valid, then the entered data is accepted as valid and stored or processed as appropriate.
