Hi. I responded to your support ticket # 86116. Here's what I said:
1. Please see Demo 20 in www.datasprings.com/formdemos where you'll find an example of calculations for a radio button. You'll also see that we use a Text/HTML field so the user can see their total. A tutorial is available below the demo.
2. Where did you set the test mode -- from the payment gateway of the module or from your Authorize.net account? If you want to see your transactions in your Settled/Unsettled Transactions, please take the module off test mode.
Let's continue our conversation on the support ticket if you have further questions. Thanks!
