Can't find my Custom Story

[i3670]

Okay, the first key (bedroom) works. Now when I try to make the other key work it says "Unexpected token '{'

{
AddUseItemCallback("", "Thronedoorkey", "Thronedoor", "UsedKeyOnDoor", true);
}

void UsedKeyOnDoor(string &in asItem, string &in asEntity)
{
SetSwingDoorLocked("Thronedoor", false, true);
PlaySoundAtEntity("", "unlock_door", "Thronedoor", 0, false);
RemoveItem("Thronedoorkey");
}
