Ok, sorry for my late reply. I got caught up in a fight with easterbunnys over some extraordinary large, fruitty and fertile eggs. Some creatures take Easter just to serious and it is not even mating season ! Can you believe that ? :-) Anyway, the underlying goal was to verify user input and to split up the date so that I could easily convert it to another format. Among others, an url and for a database querry. And I have succeeded in that. Thank you again; for taking the time to explain - and to question.
