    NSMutableArray *valueArr = [[NSMutableArray alloc]initWithArray:[fetchDict allValues].mutableCopy]; 


    for (NSMutableArray *one in valueArr) { 
     if ([one isKindOfClass:[NSMutableArray class]]) { //Check if array here 
      for (NSMutableArray *two in one) 
      { 
       cell.textLabel.text = [NSString stringWithFormat:@"%@",[two valueForKey:@"Note"]]; 
      } 
     }else { 
      NSLog(@"Program stops because this one: %@", one);
