             * but decided not to because it will create accounting discrepancies.
             * Example, user registers for 2 different events, $30 and $35. Total $65.  Makes payment for
             * $65 and the first event shows as paid $65 in event overview, the second event 0.  If I were to show amount_pd

             *
             * Suggestion.

             * Since the event cost for each one of the events in the shopping cart is now being recorded in total_cost, I
             * suggest the total payment due be the sum of those fields, grouped by the session id.  After the payment is made,
             * and is successful, the query below can be adjusted to amount_pd=total_cost.  This way, each registrant group
             * will have the correct amount associated with their registration.  From the above example, on the
             * admin attendee overview, for the firs event it will show $30 and for the second event it will show $35, the correct amounts.
