Hi Jack,
Thanks, your solution could work too, but I prefer Ian his solution. I
only have to index the data once, and the solution takes place in an easy
place in the business logic.
But perhaps, somebody else with this problem could use your solution.
Happy that you've posted this solution as well!
Kind regards,
Jochen
