STAFF_DOB = STAFF_DOBVar.get()
STAFF_CONTACT = STAFF_CONTACTVar.get()
STAFF_EMAIL = STAFF_EMAILVar.get()
STAFF_ADDRESS = STAFF_ADDRESSVar.get()
STAFF_POSTCODE = STAFF_POSTCODEVar.get()

conn=sqlite3.connect('Database.db') #opens the database
cursor = conn.execute('SELECT * FROM STAFF')
cursor.execute('UPDATE STAFF SET STAFF_FORENAME = ? ,STAFF_SURNAME=? ,STAFF_DOB = ? , STAFF_CONTACT=? ,STAFF_EMAIL=?, STAFF_ADDRESS=?  ,STAFF_POSTCODE=? WHERE STAFFID = ?', (STAFFID,STAFF_FORENAME,STAFF_SURNAME,STAFF_DOB,STAFF_CONTACT,STAFF_EMAIL,STAFF_ADDRESS,STAFF_POSTCODE))
