jens,
thanks for your reply. It helped me a lot.
Do you have me a tip how I can get all Z SQL Methods in an selection field.
I've found the superValues('Z SQL Method') function, but I'm having problems
using it, because it can only be used in python.
So how can I get the result returned from this function in my dtml form?
thanx in advance
