Last EventId

EventId is used to set in the control sheet (example) for training/conference registration to generate unique invoice id for paypal transaction, e.g. CIC-A-5, where A is the EventId, 5 is the sequence of registration for the event (5th in this example).

• The invoice id needs to be unique or else people may experience unexpected behavior when making the online payment thru PayPal as PayPal may misrecognize it as "you have paid for this invoice" and simply ignore it.

It is advised to follow the convention of coming up with the new EventId this way: follow the sequence of the last EventId (consult the table below), going from A to Z, then AA, AB to AZ, BA, BB to BZ, .. and so on.

Record the new EventId below.

It is thus okay to delete the old entries in the table below.
