Hi Jessica, Summary settings page allows you to select the relevant fields for the form for the Amount, Discount, Tax, Delivery Fee, Tip, Net amount option. The mapping in the Summary settings allows Neartail to identify the field with the amount to be charged and pass this amount to the selected the payment option such as Stripe or Paypal. If you have mapped a field for the Net amount option, the answer for that field will be passed to Stripe. Otherwise, the answer for the field mapped for the Amount option will be passed to Stripe. You will get an "Invalid amount configuration" error if the Amount, Net amount options are not mapped correctly. You had configured the discount, net amount field in the form and then deleted it after the payment was set up. That's why you are getting this error. Login to Neartail > click on the form to open it > Edit page will be displayed > In the Neartail edit page, click on the gear icon next to the form title > Form settings page will be displayed > Click on the configure fields icon next to the Save button > Summary settings page will be displayed > Order amount field will be selected for the Amount option, None will be selected for the Discount, Net amount option > click Save. You can then submit a response to test the form. Please try this and confirm.

Thanks so much for the step by step, it worked!

Thanks for the update Jessica.

this doesn't make sense to me, i need help.

Hi April, You have only added the order amount calculations in the form. You just have to map the correct field for the Amount option in the Summary settings. If you are using the new editor (Google Forms like interface), click on the form title to select it > 4 icons for preview, upload banner image, change layout and gear icon for Form settings will be displayed > click on the gear icon > Form settings page will be displayed > Click on the configure fields icon next to the Save button > Summary settings page will be displayed > Order amount field will be selected for the Amount option and click Save. You can then submit a response to test the form. It will work.
