**Kevin_G**It is possible to perform calculations based on the selections made on the Ticket Purchases widget, but the options need to be separately configured so each available option should be a widget.

The price also needs to be included in the ticket type, then the Form Calculation widget will allow to get the price once an option has been selected so you can get a total amount due.

Do note that you should not use numbers on your ticket names, otherwise the number will be also counted in the calculation widget, so the price should be the only number.

Here is also an example about how this should work: https://form.jotformpro.com/62364965575974

Here is also a guide that will provide you more details about performing calculations on your form: https://www.jotform.com/help/259-How-to-Perform-Form-Calculation-Using-a-Widget

Hope this helps.

**TBSE**Where and how do I integrate STRIPE for payments once I have all of the calculation features integrated?

Thanks,
