There's something wrong with my code, for I get this error message:
![[Image: Error.png]](http://i477.photobucket.com/albums/rr136/karai16/Error%20messages/Error.png)
This is my code, can somebody see what's wrong with it?
void OnStart()
{
    AddUseItemCallback("", "RoomKey", "RoomDoor", "UsedKeyOnDoor", true);
    SetPlayerInteractCallback("RoomKey", "Activatebob", true);
}
void UsedKeyOnDoor(string &in asItem, string &in asEntity)
{
    SetSwingDoorLocked("RoomDoor", false, true);
    PlaySoundAtEntity("", "unlock_door", "RoomDoor", 0, false);
    RemoveItem("RoomKey");
}
void Activatebob(string &in asEntity)
{
setEntityActive("Bob", true);
}
and yes, I'm sure I named my servant Bob.
