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
