We have a custom field on each of our events (custom post type) that determines the price of an event. That custom field value is used as the value in the "price" parameter, set up on the "Pricing Fields>Product" field, that is in shortcode that generated the form. The value shows up correctly in the hidden field for the Price, but the total isn't being affected by that value. How can we get the Total field to receive the value from the Price field?
