Thanks, that's a great help. I was a little confused there for a moment

No doubt I'll end up getting confused again , and it's good to know that there are people on the board willing to help.

It's amazing how boards often don't.

I think most of the problems comes from the tutorials that were written for the web site. They are nice and very instructive but I think they need some updating. I'll see what I can do about it, I'll try contacting the authors.
