How to display the total on my order form?

Hi there. I'm creating an order form and want to know if there's a way to include total $ amount of order before the client hits submit. Thank you for your help.

You may consider added a payment field to the form for configuring the products so that the total can be calculated and displayed automatically on the form. Please refer to the guide below that can help you with setting an order form.

If you are using normal fields for displaying the products and wanted to calculate the total manually, you may use the calculation widget to perform calculations on the form. Please check the guide to see how the calculation widget can be used.
