Gotcha! Yes, definitely, Guittta's are very good, and very useful, not to mention unique approaches to things which I would never have thought of. Yours' too, particularly the technique of making new trees from existing ones by combining them. I hope maybe one day I'll have some of my own to contribute. :) As Bloodsong once mentioned, we really need some "function" tutorials, hint hint. I've found a few here and there from other sources, and I'm going to be emailing the authors to see if they can be posted here, as well. Soon as I get it all compiled, that is. BTW, I asked in the Moderators' Forum about having the names changed. It's just a matter of waiting now. :) Cheers, Mike
