Since cash funds and the donations made towards them are not managed by or traceable by Babylist, we don't have a way to set a goal for those cash funds and there's no way for us to verify how much money had been put towards that goal by your Gift Givers. You can find out more here.
If you'd like to let Gift Givers know the value of a particular fund though, you're welcome to add that information in the note box on the cash fund when you add it to your registry.
