My Authorize.net payment box does not display the total

Hello,

I have used the multiple item check box and I have assigned them a calculation value of $100 each.

My Authorize.net payment box does not display the total for the checked boxes.  It wants me to enter the amount.  I am confused how to do this.

What is the form in question? If you are looking to pass a calculated total amount, to your payment field, please check this guide: https://www.jotform.com/help/275-How-to-Pass-a-Calculation-to-a-Payment-Field
