If your wedding budget changes after you have created your online budget, you'll need to update the information in the Wedding Budgeter to adjust estimates and advice. You should also keep your guest and attendant numbers up-to-date, so that per-head costs are accurate.
To change any of your budget summary information:
1. Type the new budget, guest, or attendant values over the existing values in the Toolbox column on the Wedding Budgeter page.
2. Click the UPDATE button to save your changes and adjust your budget calculations.
