Please update the checkout process to automatically calculate and display the grand total for donors. Currently, the system shows "Estimated annual total" and "Estimated annual match total," but donors have to manually add these amounts together to see the full impact of their contribution. For example, if the "Estimated annual total" is $1,300 and the "Estimated annual match total" is $1,000, the grand total would be $2,300. Displaying this grand total clearly would enhance the donor experience and help them better understand the full impact of their donation.
