Great Bluefox, great support.
I tested it and it seems to work very well, that's what I tried to do.
I did not ask the team to CB because they do not know the code EventList and can not tell me where to enter the query.
I want to ask just a confirmation. The query works only if the event is "add event" and not even if the event is "edit event".
I need the query only to insert new event.
Thanks again for the help you have given me
