Vehicle Script Help

I found a way to spawn in a vehicle but when i enter it it goes *boom.* All I did was edit the Just-a-box script. Any help please appreciated.

<sup>_classname = "UH1H_DZ";
_dir = getdir player;
_pos = getposATL player;
_pos = [(_pos select 0)+1*sin(_dir),(_pos select 1)+1*cos(_dir), (_pos select 2)];
_box = createVehicle [_classname, _pos, [], 3, "CAN_COLLIDE"];
_box setDir _dir;
_box setposATL _pos;

_inventory = [
//"Binocular",
];

titleText [format["Heli spawned nearby."],"PLAIN DOWN"]; titleFadeOut 4;

clearWeaponCargoGlobal _box;
clearMagazineCargoGlobal _box;
clearBackpackCargoGlobal _box;

{_box addBackpackCargoGlobal [_x, 0];} forEach _backpacks;
{_box addWeaponCargoGlobal [_x, 0];} forEach _inventory;
{_box addMagazineCargoGlobal [_x, 0];} forEach _items;
{_box addMagazineCargoGlobal [_x, 0];} forEach _skins;
{_box addWeaponCargoGlobal [_x, 0];} forEach _weapons;
{_box addMagazineCargoGlobal [_x, 0];} forEach _ammo;
{_box addMagazineCargoGlobal [_x, 0];} forEach _explosives;
