Best,
Maybe I'm not completely clear about it, I write, as you see above my own code, and with an example, that may be from another project or self-written, how it is with groups, how to deal with that, an example with perhaps some explanation help me on my way. Examples are given in full on the forum, are we here to help each other? Do not ask for ready-made solutions, but explain about groups, how that works. But I do not want any discussion about that, I'll be wrong, my apologies if it happened that way. I will do my homework better. Sorry for posting.
