Problem with accurate Total Cost showing on Payment Page

Hello,

When people enter their credit card information, Jotform payment page shows Total Cost: $0.00 instead of the correct fee.

This is confusing some of our students.

Shouldn't the Total Cost be listed as the amount paid from the credit card? How do we make that change so that Total Cost shows the price of the class and the correct amount the credit card will be charged?

Thank you.
