We understand there may be reasons you’d want to reset totals, but to protect our donors, once donations have been received, the amount collected currently cannot be reset.
That said, if what you're really after is keeping visitors from seeing the amount raised, you can remove your Fundraising Goal — registries without a goal show a simple "Donate" option instead of the amount raised toward a goal. You can remove or adjust your goal from the front of your registry (click "edit" next to Support Registry) or from Organizer Dashboard → Edit → Fundraising Goal. There's no need to disable donations for this — disabling donations stops new support entirely.
If you’d like to talk through your situation, we’re happy to help.
