Pass data to NSMutablearrays between two viewControllers, IOS 4.3

I am trying to pass an object in NSMutablearray to another view's NSmutableArray

I have been looking related question but couldnt figure out whats wrong.

my view switches correctly but it doesnt pass the object in my NSmutable array

- (void) tableView: (UITableView *) tableView didSelectRowAtIndexPath: (NSIndexPath *) indexPath {

    StartHuntViewController *startHuntController = [[StartHuntViewController alloc] initWithNibName:@"StartHuntView" bundle:nil];
    startHuntController.modalTransitionStyle = UIModalTransitionStyleCrossDissolve;
    [self presentModalViewController:startHuntController animated:YES];;
    startHuntController.forStandButton = [stands objectAtIndex:indexPath.row];// doesnt work
   // startHuntController.standLocation.text=[stands objectAtIndex:indexPath.row]; // this works
    [startHuntController release];

    [self.mytableView reloadData];
}

view i am trying to pass data is 

.h file
@interface StartHuntViewController : UIViewController<UIApplicationDelegate,CLLocationManagerDelegate,CoreLocationControllerDelegate> {


    NSMutableArray *forStandButton;


}
@property (nonatomic, assign)NSMutableArray *forStandButton;
.m file

@synthesize forStandButton;

what should i do ? i guess there is nothing wrong with code?

changed assign to retain, move the line startHuntController.forStandButton = [stands objectAtIndex:indexPath.row];

- (void) tableView: (UITableView *) tableView didSelectRowAtIndexPath: (NSIndexPath *) indexPath {

    StartHuntViewController *startHuntController = [[StartHuntViewController alloc] initWithNibName:@"StartHuntView" bundle:nil];
    startHuntController.forStandButton = [stands objectAtIndex:indexPath.row];
    startHuntController.modalTransitionStyle = UIModalTransitionStyleCrossDissolve;
    [self presentModalViewController:startHuntController animated:YES];
    [startHuntController release];
    startHuntController =nil;


}

there are many issues here, for first look :

@property (nonatomic, assign)NSMutableArray *forStandButton;

why property is not retain?

You need to use retain in the property statement. Since forStandButton is a property of the second view, you want to make sure it is getting set. If you create a setter (setForStandButton) for it, you can put a break point in the setter method. Once you have confirmed that the setter is being called, make sure it is being retained long enough to be useful.
