Unfortunately we can't add another charity to your page once it's live.
If you want to support more than one charity you'll need to close your current page and add another one. If there are already donations on your page you can move these over as an "offline total" to your new page, however the money already raised won't be split between the charities.
We pass the money donated to your Virgin Money Giving page onto the charity once a week, so any donations already made will have been passed on.
If you need help closing and creating a new page let me know, or you can get in touch with our Help Desk team too.
