You’ll need to build a separate fundraising page for each charity, then join them together with a Team page, giving your donors the choice of which charity they donate to. You can always add a line to your story letting people know you'd like to keep funds as equal as possible.
Once you've created a page for each charity, follow these steps:
1. Log into your account and go to one of your active fundraising pages.
2. Once on your page, select "Create a team" under the page title and follow the on-screen instructions to create your team.
3. Once you have created your team page, you will need to edit the team page to allow fundraising pages for multiple causes/events to join. To do this, go to the team page you created and click on the "Settings" tab. Here, you will have the option to "allow fundraising for any cause" and/or "allow fundraising for any event".
4. You will then need to link your remaining fundraising page(s) by going to your Team page and clicking "Join the team" in the top right-hand corner. Then follow the on-screen instructions to link your other existing fundraising page(s). If you have multiple fundraising pages to link, you will need to link these one by one.
Unfortunately we're unable to split donations from one Fundraising page to multiple charities.
