More on Listener Output

[Barry Denton]

 Here is a simpler table to compile and test event returns.
 The "set data" listener should return details of each item set in the table. It returns 9 empty events rather than 10 with details.
 
 The ""Selection " listener should also return an event containing info but does not.
 
What is the cause? It seems to be in Event?
