This was exactly what I was looking for. Unfortunately, it is unreliable. If I link it to a cell that will change, it does not update when the cell does. Instead, it goes to zero, and no matter how many times I tell it to reload, it will not work. I have to delete it and then redo it every time, which significantly reduces the usefulness. I am not asking it to update constantly, only once per day. I would even be happy if it would only update when I re-opened the file, but it cannot do that either.
