 *     Element 1 - Caption of the field
 * 2.nnfields is also a 2D array used to house the mandatory fields for which the visitor has to be filled before submission
 *   Upon submission, the program will first to check whether all the stated mandatory fields are filled or not.
 *   if not so, an alert dialog will display to remind the visitor.
