Amazing! And the second exercise now.

For each subscription, show the following columns: Id, Length, Platform, PaymentDate, and PaymentAmount Also show the future cash flows, calculated as the total money from all subscriptions starting from the PaymentDate of the current row (i.e. include any other payments on the very same date) until the very end. Name the column SumPaymentAmount.

This time, instead of ROWS, we need RANGE:
