Karw, spreadsheets are also my favorite way, although I am struggling with the complex Ifs, Ands, Nors, But, Do's. Don'ts and God know what else the Excel people have created. The problem is that when I find out a way of doing something then after a while I lose it. Math I can remember. But this Excel logic stuff escapes from me.
I keep you upto date on what develops in Dutchland on the discussion forum.
Struggler,
