• When a sale is identified as not valid during the transaction process, it needs a useful error and to be returned to the selltickets page.

Errors can occur under the following known circumstances
- A 5 film pass is added, a 5 film ticket is added and then the 5 film pass is removed.  The day table will still have the 5 film ticket which is no longer displayed because it is not available.
- Tickets are added in the dm override by the session expires before the transaction is processed

• The return to ticket selling link on the dm override page needs to clear the day table so that any invalid tickets that have been added during the dm override session are removed.
