When I try to launch my story it says Masterbedroomkey was not declared... or something like that.... anything wrong here?
// Run when entering map
void OnEnter()
{
AddUseItemCallback("", "Masterbedroomkey", "masterbedroomdoor", "UsedKeyOnDoor", true);
}

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

// Run when leaving map
void OnLeave()
{

}
