I need help Validating the required data elements in this program. I need the Patient id,Patient last name Patient first name, Patient primary care physician, Patient address1,Patient city, Patient State, Patient zip. all validated (entered as non-spaces) If invalid data is ,entered, display an "invalid input of type .. Record reject" message and use the COUNTINUE statement to return to the top of the loop to allow a new entry to be made.

The <id is invalid> is pseudo code. You should fill that in yourself, based on the logic of when an ID is invalid. As I said, you could create a method "boolean isValidPatientID(String id)", then change the if to
