Hi,
I remember a reply by Bruce.
In the validation part of the form, after all rules are passed, you can write the session number into a designated field (e.g. XXX;Session) in the record (don't do this in the priming part if the template, it has to be done after 'Save' is clicked.)
Later you can run or schedule a special procedure which deletes all records where XXX:Session is equal to zero or blanks.
So yes, there is a mess. But only for as long as you allow it
