Error unexpected token

When creating a new crafting recipe in ER I put in this command

$Event(19002000, Default, function(X0_4, X4_4) {
    waitfor(PlayerHasItem(ItemType.Weapon, X0_4));
    RemoveItemFromPlayer(ItemType.Weapon, X0_4, 1);
    AwardItemLot((X4_4);
    RestartEvent();

I went to save it and It said
ERROR: Unexpected token }
432:1:});

Please help
