How to I connect Stripe with the calculation Widgets?

I am trying to add a limit on the products I sell and I am very surprised at how hard it it given how great JotForm it.

From what I can gather the only way to do this is to use the Inventory Widget and the Calculation widget which then talks to the Stripe payment process - seems very convoluted for quite simple task

Anyway all the articles seem to be of the old design of JotForm and I cant find the option to sync it with the calculation form...

Here is my Stripe options...

Here's the screenshot for the new wizard.

The new payment wizard was rolled out recently so we missed updating the guide. Anyway, we will go ahead and update it to prevent confusions. 

Thanks for bringing this to our attention. If you need any further assistance, do let us know.

We have updated the screenshots on the guide https://www.jotform.com/help/275-How-to-Pass-a-Calculation-to-a-Payment-Field

If I change the way Stripe is integrated as above will it have an effect on all of my forms?

I have some that just use the normal 'Sell Product' mode

Changing the way stripe is integrated as above will not have an effect on all of your forms. It will only affect the form where you were changing the stripe integration. So if you have a form with a "Sell Product" mode and you change it to "User defined amount", then only that specific form will have the user defined amount mode. The rest of your forms who have "Sell Product" mode will remain as is.

Please let us know if you need further assistance.
