What's wrong with my code?

[Johanis]

I can't figure out what's wrong with my code. It runs and everything, but it doesn't put in any values into the database.

 private String naam1;
      private String naam2;
      private String playup;
      private String rotate;
   
       SQLUserinfo (String nm1, String nm2, String plyp, String rtte)throws SQLException
      {
         naam1 = nm1;
         naam2 = nm2;
         playup = plyp;
         rotate = rtte;
         updateMthd("INSERT INTO Extra VALUES(naam1, naam2, playup, rotate)");     
      }

here is the errors:

You still have another tread running about the very same subject: SQL problems. I'm locking this one.
