Hi - if you are getting an invalid amount configuration error, then it indicates that the correct form field it not mapped for the Amount option in the Summary settings page. Notes for your reference. 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. Total amount calculation If you have added other fees in addition to the order amount calculation, then you must calculate the net amount including other fees to be charged. Calculate net amount (skip if already added) In the Neartail Edit page, click on the Add price field icon > select Net amount, click Next > select Standard calculation using NETTOTAL() formula, click Next > click Create. NETTOTAL function calculates the net amount based on the fields mapped in the Summary settings page. It will automatically add the fields mapped for Amount, Delivery Fee, Tip, Taxes and subtract the Discount to calculate the net amount. When you use the Add price field option, it automatically maps the fields in the Summary settings page. If you use the Add field option, you will have to manually map the fields in the Summary settings page.
