How do I change the pricing on my form?

I am customizing my form and I cannot figure out how to change the pricing for the different performance levels?

Form that you provided is created on account with username Solomon_Love. Once you login to your account, open your form inside of Form Builder and click on Payment Settings option and then click on Continue button.

After that list of your products will be shown. To edit product price, click on pencil icon and change the price.
