Stripe: How can I set the amount field to be number type.

Hello, I use a stripe payment connection with user defined amount (or donation, is the same) in my form. 

Could you change the Amount field type from "text" to "number" (or "value") so that smartphones users can use numeric keypad instead of the keyboard, when they input the amount of the transaction? 

I would recommend you to use a number field instead:

You will then need to pass the entered amount to the payment field, please check this guide that will help you doing so: https://www.jotform.com/help/275-How-to-Pass-a-Calculation-to-a-Payment-Field 

I hope this helps. 

Ok, it works! Thanks
