Your goal is determined by the total value of all the items in your Wishlist. Adding, removing, or adjusting existing Wishlist items is the way to establish or change your campaign's overall goal.
Please note: It typically isn't possible to change your campaign's goal after launch.
Note: This is separate from the dropdown where you select a range for how much you intend to raise on the Campaign page for the question, "How much are you raising?" This dropdown is mainly to help your crowdfunding specialist get a better understanding of your project goals once you submit your campaign for initial feedback, so they can help tailor their advice to the scope of your project.
